PHP :: Deleting A Node With Known Position In DOM (XML)

Select Node From DOM By ID?
I'm looking for a way to select a <div> by id from an entire xhtml page. I'm not a very experienced coder, but I'm learning... Does php have a fuction for this? it would be like

$entire_page = "entire xhtml page fetched from DB which contains <div id='wanted_div'>some content I want</div>";

$my_wanted_div = .... // how do I get the content of 'iwantthisdiv' here?

Children Of Child Node??
Is there any function or way to access the children of a child node using DOM???

I mean if i have the xml structure as:
<app>
<app_data>
<data name='method'><value>sum_dif</value></data>
<data name='val1'><value>123</value></data>
<data name='val2'><value>456</value></data>
<app_data> // child of child node
<data name='coool'><value>divo9</value></data>
<data name='sands'><value>007</value></data>
<data name='make'><value>bond</value></data>
</app_data>
</app_data>
</app>
How can I access the data in the child node <app_data>?

Writing A Node To An XML File
I want to write a node or nodes to an existing xml document. I don't need to create a new document, thanks but no thanks.

Judging from various posted topics I've seen. It appears the php DOM for XML isn't quite there yet and has a lot of bugs. Not only that it takes a few months before web hosters update versions of php.

I tried the pear classes, but they're so poorly documented, there's no example, there's nobody you can contact at Pear for hlep. If you ask for help on forums, you get no reply's so obviously not many ppl are using these classes.

I wonder..... if there's a push from say mySQL to stall or slow down PHP's functionality for XML?

Any ideas on how to write a node or nodes into an existing XML file..... without a bunch a array manipulation?

Batch File Deleting And Folder Deleting
I have a folder in my web site where I used php to create and copy in files. but now I can't delete them easily. The only way I know how that is possible is through php. I get an error the following ftp error:

550 th: Permission denied
I had the chmod() set to 0777 on every file and folder. But I still seem to loss control over the files when I try and do things with them through other means.

I think it is because the user I use to access the files via ftp a diffrent user. So I tryed to add a function with chown() for the new files I was posting and uploading. It didn't work on those new files. so it looks like the only thing I can do is use the unlink() function which deletes the files fine.

The only problem is now I have something like 100 sub directories all with files in them. I need to figure out a way to batch delete them. I can't find a script that goes through and finds all file contents including all sub directories and unlink those things.

I found some that will use a for loop to list out the contents of a folder but it is just files. No sub directories. Any body got any ideas on which functions I should use or know where a script is that I can base mine off of.

I am not sure how to approach this since what I tryed with chown and chmod has failed thus far. I currently have no code and am starting from scratch on this batch flushing of my directory.

Can $node->node_value() Return A Null Value?
I am using the following function to access a nodes value from an XML
file. It works fine until it discovers a empty tag. I would like to
have the option of leaving some tags empty for my script.

..
..
..
function foutput_contact ($node_name) {
$xml_document = domxml_open_file('xml/contacts.xml');
if ($xml_document) {
$nodes= $xml_document->get_elements_by_tagname($node_name);
$nodeCount = count($nodes);
$node = $nodes[0];
if ($node) {
$node = $node->first_child();
return $node->node_value();
}
}
}

The error is returned at the line 'return $node->node_value()' but
only when I use an empty node. Can this script be modified to allow
empty nodes?

DomDocument: Setting Attributes To A New Node
I'm trying to create a single function to append new nodes to a
DOMDocument object:

public function addElement( $element, $name, $value = '', $attrs = Null
)
{
if( !( $created = $this->createElement( $name, $value ) ) )
throw new Exception( 'Could not create a new node ' );

if( !( $child = $element->appendChild( $child ) ) )
throw new Exception( 'Could not append a new node ' );

// Process and attachs the new attributes from array $attrs if
any...
// if( $attrs )
// foreach( $attrs as $attribute => $value )
// ...
}

So far, so good. Now I want to set attributes and its values of the
recent created node (playing with createAttribute() and setAttribute(),
but I can't get the DOMElement from the new child DOMNode. Is it
possible without issuing getElementsByTagName() or getElementById() ??

Is another easy way -using DomDocument object- to create a new
element (such <table width="50%" border="0">...</table>) which has its
attributes and its values ?

After I Load An XML File, Can I Sort It By Node Attribute
After loading an xml file, is it possible to sort it by attribute?

For example, I have the following xml file:

<xml...
<diary>
<entry date="2005-01-01">I went to the park</entry>
<entry date="2005-01-03">Sold the car today</entry>
<entry date="2005-01-02">Went for a stroll</entry>
</diary>

When I go to load this using PHP, I would use some this similar to
this:

$xmldoc = domxml_open_file('diary.xml', DOMXML_LOAD_DONT_KEEP_BLANKS);

$node = $xmldoc->document_element();

Before I go storming through the xml tree outputing along the way, can
I sort it by (in this case) date?

[DOM XML] How To Encode A Node Content (Accentuated Characters)
I'm trying to generate a RSS newsfeed using the DOM XML functions. However I
can't find a way to use accentuated characters. I even tried to specify a
character encoding set but it doesn't solve the problem.

Error I get :
XML Parsing Error: not well-formed
Location: news.php?action=syndicate&format=rss2
Line Number 1, Column 102:<?xml version="1.0" encoding="ISO-8859-15"?><rss
version="2.0"><channel><title>Website title - News (
----------------------------------------------------------------------------
-----------------------------------------------------------^

The not well-formed character is an accentuated character, as you can see on
the following code sample :

<?php

header ('content-type: text/xml');

echo ('<?xml version="1.0" encoding="ISO-8859-15"?>');

$dom_doc = domxml_new_doc (Ƈ.0');

$rss_el = $dom_doc->create_element ('rss');
$rss_el->set_attribute ('version', ƈ.0');
$rss_el = $dom_doc->append_child ($rss_el);

$channel_el = $dom_doc->create_element ('channel');
$channel_el = $rss_el->append_child ($channel_el);

$title_el = $dom_doc->create_element ('title');
$title_el = $channel_el->append_child ($title_el);
$title_el->set_content ('Website title - News (àéèù)');

echo ($dom_doc->html_dump_mem ());

?>

Removing the accentuated characters from the title generates a well formed
XML file. Note that I also tried to encode the characters using the
htmlentities function but it didn't change anything.

Position In The DB
A friend and I are trying to make a highscores script for a game. Basically this stores numeric values in a column named `XP`. I want to be able to find out the rank of a user in this column.

So I thought why not do something like:

$stat_sql = "stat" . $i;
$$value = $row[$stat_sql];

$sql = mysql_query( "SELECT * FROM " . $table . " WHERE `loginID` = '$id' ORDER BY `" . $stat_sql . "` DESC" )
or die ( mysql_error() );

while ( $call = mysql_fetch_array( $sql ) ){

$new_var = $value . "_rank";
$$new_var = $call;}

But that only outputted "Array". Then I thought even if it didn't output array it would have done 1, because it's only finding one user.

I thought the only way to fix this would be to do a general select statement and then loop through all the users till I found that login ID but this script could potentially have thousands of users and I'd rather save bandwidth.

Get Key By Position
If I have an array that looks like this:

Array ( [4] => 3 [12] => 2 [20] => 1 [23] => 1 [33] => 1 );

and I want to return the key 4, how would I get that (4 won't always be the key value)?

Anchor Position
Could anyone teach me how to set anchor for a php link?

Is the following right?
www.test.com?abc=1#anchor_name

Or the following?
www.test.com#anchor_name?abc=1

Or both are wrong?

Besides, could I go to anchor position by PHP command?

Automatic Position?
I have a basic table/database set up to record a persons name, location, the number of miles travelled and their position in a race.

At the moment all of these fields have to be entred manually when you wish to update them.

Is there a way to automatically assign a position? (i.e. the person who has travelled the most number of miles 1st - least nth?

Displaying A Page At A Specified Position
I have a form about half way down a web page, which posts criteria for the
WHERE part of an sql which then returns the results at the bottom of the
page.

Trouble is when the page reloads it goes to the top of the page again so the
results are not visible and the user is sometimes unaware that anything has
happened.

I could get a message to display at the top to tell user to scroll to
bottom but i would prefer the page to display at the start of the records(in
a html table).

Modify String In One Position Only
Is it possible to modify a string in one place using an indexing operator
and an assignment statement?

E.g.:
$s = "1234567890";
$s[5] = "d"; // $s is now "12345d7890"

According to _PHP Bible_ (2nd ed., p.175), this kind of syntax can work ,
but is undocumented and, moreover, appears to be discouraged because "almost
all PHP string manipulation functions return modified copies of their string
arguments rather than making direct changes, which seems to indicate that
this is the style that the PHP designers prefer."

I did a google search (both www and USENET) and found nothing on this.

Position Of String Occurence
I have a string like "lalala: djkahsd : dajkdassd : adasd :"

Is there a function to find the position of the "I"th occurence of a
character/string? Like lets say I want to find out the position of the
second colon. How do I go about that?? I can only find functions that
return the position of the first or last occurence, but not a variable
occurence ::sniffles::

Keeping Scroll Position
I want to keep the scroll position after reload. I tried this:

White Space Position
how do i find if there is white space in a string eg. "hello how are you?" also how do i return the position of that white space?

How To Position The Page To The Center?
I'm trying to wrap a certain website and then make it load to the center position automatically when the page is loaded. I tried anchor but it doesn't seem to work. And the main menu of that website seems to align itself according to the width specified - but I need to the iframe to be 300 pixels.

<div align="center"><iframe src="www.phpfreaks.com#Summary" width="300"></iframe></div>

Or how to make them position to where their last scroll position is the next time when they click the links inside the iframe?

Arrays: Inserting At Current Position
I've trying to insert a new element in a numeric array for the past hour with no luck. I came close but didn't succeed.

I thought of slicing the array into two others pushing the new element at the bottom of the first slice and merging with the second.

The problem is though that the second slice's keys are left intact so the new element of the first slice gets overwritten after merging since it has the same key as the second slice's first element.

I tried array_unshift to reindex the second slice by adding something to the top of it but what I should really do is reindex without adding because that something would also overwrite the new element.

So, is there a way doing an insert (= pushing down once all elements at current position and getting in the place of the current element) in an array?

Counting Position Of Character In String
I am trying to calculate the postition(s) of a certain character in a string.
e.g (a binary string) ??', I want to calculate the Ƈ' in the whole string and returning the charatersplace like Ɖ|4|7', meaning that the 1 appears in the 3rd,4th and 7th position in the string.

Roll To Web Page Vertical Position
I have a php web page which lets users to select choices from combo
box and submit the page to update the item description. However, when
I have many items on the same page, the row position reset to the
beginning of the page. So this makes trouble to the users that he has
to find again the product item row position to see the item
desctiption.

Could anyone tell me how to automatically roll the web page to the
vertical positon which is same as previous page?

Get The Position Of An Uppercase Character In A String
Does anybody know how I can get the position of an uppercase character in a string?
For example, lets say I want to find the position of the second Uppercase character in the string: "HelloThere", which is the "T".

Position In Array In A Foreach Loop
I have a script that checks an array for names and if that person's name is there it will e-mail them a particular variable.

Here is the setup:

an array such as $names = array( $name1, $name2, $name3, $name4 ); etc.

Then a foreach loop
foreach ( $names as $person ){
if ( $key == 1 ){
$color = blue;}}

However I need something that will get the position in the array of the variable that the foreach loop is dealing with. I tried array_search but that gets screwed up if someone is in the array more than once, it will then only stop at the first time they are in the away.

Getting The Position Of X Occurance Of A Char In A String
I know that strpos gets the position of the first occurance of N character in a string and that strrpos gets the position of the last occurance of N character in a string.
But say I have a string that has 5 :'s in it.

a:b:d:c:e:f
How would i get the position of the Xth occurance, say, the 3rd.
I've been looking all around and havent really found anything, maybe I havent researched it extensively enough.

Getting The Current Position Of A Cursor In A Text Box
Say a user has their cursor in a text box and they click a button and want to add some information in, how would I get the current position of the cursor in the textbox to add that information in to that specific place?

Explicit Numeric Keys Vs Item Position
Say if I have a mixed array:

$array = array("item1", "2"=>"item2", "5", "item4key"=>"item4")

Is it possible while looping through the array (foreach ($array as
$key=>$val)) to check if an item has an explicit key specified instead
of its automatically assigned position key?

Call Variable Based On Array Position
wondered if it's possible to call a previously set variable(s) by using an array position. For example if I have variables myvar01, myvar02, myvar03 can I somehow call these in a loop, interchanging the numbers? Here is a simplified version of my code:

Output An Image Directly At A Particular Position In The Browser Window
Is it possible to dynamically create an image (jpeg/gif/png) and output
it directly at a particular coordinate position in the in browser
window using PHP GD functions and HTML (if necessary)?

Imagemagick - Position A Image On Top Of Another Image
I am trying to put a small transparent gif or png image in the top left corner of my images with imagemagick.

Need Help With Deleting Records
I'm trying to add a link on the display of a record to delete that record.

The main part of the record is stored in pw_event, then there are several rating fields for that record stored in pw_rate, and there is also several records for the first record stored in pw_whois.

I need to have a link that will deleted everything for that record in all three tables.

Here is my display script:

PHP Code:

Deleting Last Comma
The code below displays pet names like so:

Fido, Bowser, Kittycat, Spot,

and I want to delete only the last comma. I tried 'substr' and 'rtrim' and both of those delete the space and comma between each name, not just the last name as I'd like, so I end up with:
Fido,Bowser,Kittycat,Spot,

How would I delete only the last comma, so that it is this instead?
Fido, Bowser, Kittycat, Spot

Even with trim and substr, I end up with:

Deleting A Session
I want to be able to delete a session so that the next time there's a call to session_start, it creates a new session ID. I don't want to destroy the session variables specifically (though this will be a side-effect of what I'm doing) so I know that session_destroy isn't what I want to do.

I presume I should just delete the session cookie manually. Is there a neater way? And if not, how do I do this?

Deleting A Director
I'm using this code trying to make ato delete a file or folder under w2k, apache.

$direct=split("repadmin.php",$PATH_TRANSLATED);

header("Location:repadmin.php");
exit;

but return this warning:

Warning: unlink(1) [function.unlink]: No such file or directory in c:program filesapache groupapachehtdocsguonline epositorio epadmin.php on line 94

I checked the whole path and looks good.

Deleting Files
The below should delete files from a dir older than a week. I set the $dtime to 0 to test the script but it deletes nothing. What is wrong? Code:

Deleting Files
I'm using different files to store some arrays to make administration of a very small job-logger very easy. I currently read the file, remove the element to be deleted, delete the whole file, and write the file again without that element. Is there a way to remove a single element out of that file without deleting the whole file?

Deleting Cookies?
For some reason is i set my cookies like this PHP Code:

Deleting A Record.
One last (hopefullly) problem I can't seem to get around for this
program...why isn't this deleting the row i want? It does nothing. Now error
messages either. HELP!

$link = mysql_connect("localhost");
if(! $link)
die("Could not connect to MySQL");

$database = "PC_Store";
mysql_select_db($database)
or die ("could not open $database: ".mysql_error() );

$result = mysql_query("DELETE FROM inventorydata VALUES('$ProductID')");

The $ProductID variable is brought in from a menu choice on a diffrent page,
it is also the primary of the table...so it should delete the whole row
right?
