String Function In PHP To Make The Searching Of Tags
I not sure if bbcode was the term for this.. how this can be done? for example in this forum, with the open and closing some code here or [/img]link of image here[/img] and on the display it is display with a ceratin CSS/format or something..is this can be done through "eregular expression"? and before saving on the dbase is converted to <img src"" />? am I right? 

is there a string function in PHP to make the searching of tags easy?

Make Text String Read From Right To Left In Imagettftext() Function
I want to write a text string from right to left instead of from left to right with the imagettftext (); function

I read in teh manual that the angle variable controls this, it says that 0 angle means left to right, so I tried 180, 360 but nothing happens

What angle do I need to put it to get it to write it right to left

I am writing a hebrew text string with a font.ttf that supports hebrew characters

<?php   
$white = imagecolorallocate($background, 255, 255, 255);
$fontfile = "davidtr.ttf";
$string = "&#1502;&#1495;&#1500;&#1491;&#1490;&#1499;";
imagettftext($background, 12, 360, 3, 17, $white, $fontfile, $string);

Make Associative Array Out Of String
I have a string that look something like this:

$string = "weight, kg|1200|width, mm|220|prize|20000";

and I would like it to an associative array and print keys and value:

width, mm: 220
prize: 20000

(The string above is fetched from a database)

Anyone have any bright ideas how to do it?

Is It Possible To Make Your Own Function For Encryption?
I am sorry for bringing up *yet another* post about encryption, but I was just curious. Is there a way to make your own encryption function? I mean, that would make it more secure than anything, right? Since no one else would have that encryption key or whatever? Is there a way to look at the current encryption functions like MD5 or crypt? I know it's a lot more complicated than a=1 and b=2, but I think it'd be cool if I could come up with my own form of encryption (with the help of a professor, of course)!

Make Ip Block Function
I would make a ip block script for my site. The blocked ip are stored in a
file.
I have made the following script. Why does this not work. The file entries
must be stored in a array and after that i must check all the fields in the
array. Please help...

<?php
$ip = $_SERVER['REMOTE_ADDR'];
$bestand = "ipblock.txt";
$open = fopen($bestand, "r");

$iparray = file ($open);

$n = 0;

while ($n < count($iparray)) {
if ($iparray[$n] == $ip) {
print ("NOT");
else {
print ("YES");
$n++;
}
}

Make $_SESSION Variables A Global In A Function?
i'm have a particular function where it creates session variables, yet after using this function i want to immediately use these session variables

now I realize the only way to "use" variables that are made inside of a function is to make the variable a global variable so it can be used outside the function

so i did this:
global $_SESSION['userid'];
global $_SESSION['username'];
global $_SESSION['userlink'];
global $_SESSION['userifnewmsgs'];
global $_SESSION['userrank'];

however there are many instances when !isset($_SESSION) , when the session variables are not already set

i run this function when the sessions are not set and I get this:
Parse error: parse error, unexpected '[', expecting ',' or ';'

what's going on and how can I fix it?

Make Thumnails Of A Video - Ffmpeg Function GetFrame()
I have coded a script that makes thumnails of a video. here is my code:

10) $mov = new ffmpeg_movie($videospath);
11) $duration = round($mov->getDuration(),0).'s'
12) $height = $mov->getFrameHeight();
13) $width = $mov->getFrameWidth();
14) $image = imagecreatetruecolor($width,$height);
15) $frame = new ffmpeg_frame($image);
16) print is_object($frame)." obj1 ";
17) $frame = $mov->getFrame(1);
18) print is_object($frame)." obj2 ";
19) $image = $frame->toGDImage();
20) @imagejpeg($image, $videospath.$vid.'.jpg', 100);

This code works fine for some movies and makes the thumbnail image but for
some movies it did not make thumnails and give the following error.

1 obj1 obj2
Fatal error: Call to a member function on a non-object in
/home/iideshow/public_html/inc/makeVideoPics.php on line 19

In try to debug the error I add two extra statements in my code on lines 16
and 18 and u can see in the output before the calling of function
$mov->getFrame(1); on line 17 the frame object exists but on line 18 it is not.

Can any one guid me wht's the problem here.
Remember it works on some videos but on most of the videos it did not.

Parse Part Of String (mid String Function ?)
Can someone tell me how to parse part of a string? I can use the following:

<?php
$text = $_SERVER['PHP_SELF']; //$PHP_SELF //(document.url);
echo $text;
?>

to get this result:

"Your currently at /test.php "

I just want to get "test.php " without the dash. I also need to parse out
parts of other strings. I know how to use Mid(), Left(), and Right() in VB,
but no clue for PHP.

Two Equal Strings?
I was just checking php.net but couldn't find a function that will compare to strings.

If there isn't a function, could you give me an idea of the coding that would compare two strings?

When To Use 2 Equal Signs And When To Use 3
When I had these two lines in my code:

if ($executed == "The command didn't exist") {
$this->core->error("In CommandRenderAllActionsInAnArray we sought
the command '$commandName' but ExteriorCommands could not find it. It
returned the value: '$executed'.", "CommandRenderAllActionsInAnArray");

I was getting this on screen:

# CommandRenderAllActionsInAnArray threw this error: In
CommandRenderAllActionsInAnArray we sought the command
'checkToSeeIfThisIsTheFirstLogin' but ExteriorCommands could not find
it. It returned the value: &#391;'.

But if I change the first line to this:

if ($executed === "The command didn't exist") {

then it works correctly.

Why does this need 3 equal signs? Why doesn't 2 suffice? I've done
string comparisons before and I've never had to use 3 equal signs
before.

Strcmp Vs Equal
I noticed in some examples to the encrypt functions of the PHP manual a
syntax was used for password checks such as

if (strcmp($userpassword, md5($_POST['password'])) == 0) {
// do login

What is the advantage of this compared to

if ($userpassword == md5($_POST['password'])) {
// do login
}

How Can One Variable Equal 2 Things?
I'm having a problem that is baffling me... say I set a session variable
as so:

$_SESSION['temp'] = "default";

Now if I test the following two conditionals:

if($_SESSION['temp'] == "default")

and

if($_SESSION['temp'] == 0)

they both return TRUE. I don't understand why this is... if anything, I
would have thought testing if it == 1 would be a boolean true since the
variable exists and is not NULL, but testing if == 1 returns FALSE.

Two Variables, Equal Values - ?
After seeing a script programmed by a user in the beta-test section, I copied its premise - a man vs. dragon battle, with random damage being done.

It just takes random numbers each time the page loads for damage values. That's all it does. However, whenever I play it, the end HP for both man and dragon are exactly the same.

I need 2 things done, or at least to know how to do them -

1) I need to know how to fix the equal-HP problem
2) I would like it if someone could tell me how to achieve the effect of a
<br>...tag within a PHP script.

Here's the script! Code:

Equal Ratio Image With Netpbm
I'm trying to modify a script I am running for a gallery application. The script creates thumbnails properly, but only changes it based on width, which is a variable supplied in a sql table. I'm trying to modify the script so that it so that the width "and height" are no greater than that variable. Here is what I have so far:

Code:
<?php
function RatioResizeImg($src_file, $dest_file, $gid) {

list($dbconn) = pnDBGetConn();
$pntable = pnDBGetTables();
$column = &$pntable['meg_categories_column'];
$query = "SELECT $column[thumbwidth] from $pntable[meg_categories] WHERE gallid=$gid";
$result = $dbconn->Execute($query);
list($newWidth) = $result->fields;
list($newHeight) = $result->fields;

switch(megConfigGetVar('imageSoftware')) {
case 'GD': return RatioResizeImgGD($src_file, $dest_file, $newWidth); break;
case 'ImageMagick': return RatioResizeImgImageMagick($src_file, $dest_file, $newWidth); break;
case 'none': return $src_file; break;
case 'browser': return 'browser' break;
case 'NetPBM': return RatioResizeImgNetPBM($src_file, $dest_file, $newWidth, $newHeight); break;
default: return $src_file; break;
}
}

function RatioResizeImgNetPBM($src_file, $dest_file, $newWidth, $newHeight) {
/* Define where to find the various external binaries we need */
$netpbm = megConfigGetVar('netpbmPath'); /* default: home/www/pcmodeler/netpbm */

$djpeg =$netpbm."/djpeg"; /* decompresses a jpeg to ppm */
$cjpeg =$netpbm."/cjpeg"; /* compreses a ppm to jpeg format */
$pnmscale = $netpbm."/pnmscale"; /* scales a ppm image */
$pnmscale = $netpbm."/pnmscale"; /* scales a ppm image */
$jpgtopnm = $netpbm."/jpegtopnm"; /* convert a jpg to ppm */
$giftopnm = $netpbm."/giftopnm"; /* convert a gif to ppm */
$pngtopnm = $netpbm."/pngtopnm"; /* convert a png to ppm */
$ppmtojpg = $netpbm."/ppmtojpeg"; /* convert a ppm to jpg */
$ppmtogif = $netpbm."/ppmtogif"; /* convert a ppm to gif */
$ppmquant = $netpbm."/ppmquant"; /* colour quantize a ppm */

/* $imginfo = @getimagesize($src_file);
if ($galleryvar['imageSoftwarePath'] == '')
$cmd = $galleryvar['imageSoftwarePath']."/";
else
$cmd = "";
*/

if(!file_exists($dest_file)) {
if(ereg(".gif$",$src_file)) { /* Look for .gif extension */
exec("$giftopnm $src_file | $pnmscale -width $newWidth ".
"| $ppmquant 256 | $ppmtogif -interlace > "$dest_file"");
} elseif(ereg(".jpe?g",$src_file)) { /* Look for .jpg or .jpeg */
exec("$jpgtopnm $src_file | $pnmscale -xysize $newWidth $newHeight".
"| $ppmtojpg > "$dest_file"");
} elseif(ereg(".JPE?G",$src_file)) { /* Look for .JPG or .JPEG */
exec("$jpgtopnm $src_file | $pnmscale -xysize $newWidth $newHeight".".
"| $ppmtojpg > "$dest_file"");
} elseif(ereg(".png",$src_file)) { /* Look for .png */
exec("$pngtopnm $src_file | $pnmscale -xysize $newWidth $newHeight".| ".
"| $ppmquant 256 | $pngtopnm > "$dest_file"");
} else { /* not a GIF, PNG or JPG file */
return("");
}
}
return $dest_file;
}

?>

So far, I can't get it to modify the width, so that portrait images are no larger than the variable. What am I missing?

Multi String Function
I am trying to create my own template engine.. nothing serious just for personal use but I want to make a certain function that I do now know how to make.. basicly it should work like this template($templatename, $var1, $var2, $var3);

though the $var's will be different each time, so with one template it'll only be one var and with another 5.. and I have no idea how to get that done. I want the function to get the template from the database and convert [var1] to $var1 etc.

Translate String To Function Arguments
I have this:

<headline size="2" color="#000000">Hello World!</headline>

I have already done all the coding to pass this to a PHP function this way:

function headline($content){
print "<span class='headline'>$content</span>";
}

So the <headline...> example would result in:

<span class='headline'> Hello World!</span>

So far so great. But you might have noticed the arguments in the original
string? I want to pass those! I would prefer to have them this way:

headline("Hello World", "color=#000000", "size=2");

And then extrat them with func_get_arg(). But how do I translate a string to
seperated arguments for a function?

Conditional Loop
I have one table, "players" that has player info including start season (year). I then have a table for each season with player stats, i.e. games played etc called stats200X where X is the year obviously.

I have no problem with extracting data from the current year, but what I would like to do is get data from previous years too. I was thinking about doing something like:

(year) - (startyear), which for example could be 3.

I don't know where to begin, but I want to be able to loop though previous years so that, if tables exist of course, I could do

select * from stats{Y -1}
display
select * from stats{Y -2}
etc

Would I need to hard code this or is there a way of doing this though a conditional loop?

Sessions + Conditional Include
I am having a little problem in trying to figure out why my session state is not expiring after I close the browser window. Having been used to the ASP way of doing things I am trying to get my head around this slightly different method of handling sessions in PHP....

What happens is that I log on to the site, do various things and then close it when I am finished. I return the next day to find that the 'logged in' menu is displayed first which shouldnt happen until you have logged in again.

I assumed that the session was been stored as a cookie but wasnt been released after the session terminates by default, but found I was wrong when I deleted all my internet files and went back to the site.

My code for the first page is as follows..

Writing Conditional Statement
I'm trying write a conditional statement that updates the database in 1 of 2 ways depending on the values given. I'm only 2 weeks into learning PHP/MySQL so I realize the way I've written it out is probably sloppy and more inefficient than what it could be. I've just been winging it from examples and trial and error and have gotten everything working except for this. I'm not sure if I have my logic or syntax wrong.

Application-specific details:
This is a simple invoicing application. Every invoice is in either 1 of 3 states:

- pending (default state when a new invoice is entered)
- paid (state when invoice is paid in full)
- partial (state when only partial payments have been made on the invoice)

What I'm trying to do is this:

1. If a partial payment is made on an invoice, the status is set to 'partial' (this is working)
2. If the payment posted was the full amount of the invoice or the final amount needed to pay it in full, the status is set to 'paid' (this is not working)

My processing logic works like this:
1. There is a total invoice amount stored in the invoice table represented by $total variable (working)
2. When payments have been made to that invoice (stored in the payments table), I show the remaining balance on their invoice by calculating the sum of those payments and subtracting them from the total (this is represented by the $diff variable and is working)
3. The part not working: When the remaining balance ($diff) minus the payment amount posted ($_POST['amount']) is equal to 0, the status is set to paid. PHP Code:

Conditional Statements And Loops
Not long ago I was asked to give PHP lections to some private IT
school. I'm on second lection now, and will be teaching my :) students
conditional statements (if..else and switch) and loops (while and for).

Can you give me an advise on some geeky use of those statements to stir
up some enthusiasm in students.

Mutlipart And/or Conditional Form
I have a form that needs to have conditional statements, and I am not sure how to "fix" this. The existing form is split in two parts - the form, and the processor. I would think that I will need to combine them, but..

Anyways - what I need is somewhat simple - if a certain option (from a <select>) is chosen, force another field to be completed. I also have 2 other fields that if the radio button is set to YES, require new fields. Ideally, the optional fields would only be shown to the user IF they are required.

Conditional Select From Mysql
I have a mysql database which stores race data that I want to open up to users for viewing. I want the user to be able to select various subsets of the data according to the parameters: race, gender, age, and type (and maybe sometime, by name as well). This is BOTH a mysql question and a php one, as I ask for a more efficient solution (see bottom this post).

Here is a snippet of how I am implementing the mysql statements to select only the exact subset of data. PHP Code:

Conditional Preg Match

it does something else/sets it to something else?

Question On Conditional Statements
I'm a perl programmer and am trying to learn PHP.

So far I have figured out most of the differences, but have not been able to
find out how to do the following:

When running through a loop, how can you test two separate conditions
against the same $element of an array. For example, this is how I thought it
would be done (similar to Perl), but it did not work:

if (eregi("apple", $line) and (eregi("orange", $line) {

do whatever;

}

Basically testing each line of an array to see if both the words "apple" and
"orange" are present.

Also, is there any equivalent to the following from Perl while running
through a loop:

next if (whatever conditions);
last if (whatever conditions);
