PHP :: Deleting Rows On Text File

Deleting A Line Of Text From A Txt File From A Form
How can i delete a line of text from a .txt file using a form?

because i have a form right now that saves information from a form to a txt file for news, now i need to know how to make it so i can delete it from a form.

also, if you know how, how do you overwrite lines of text in txt files from a form?

Deleting Lines From Top Of A Large Open Text File
I am splitting up one huge text file in several smaller files to prepare them for database processing. So far I tested it with files up to 100MB and everything works fine.

Now here's my question: To optimize my script I would like to incrementally remove all lines form the original file which have already been copied to the smaller file.
This would speed up reading the original file in each loop.

Unfortunatelly I couldn't find a way to remove/delete lines from an open file. Of course I could read the whole file, delete the lines and then write it back. But for files bigger than 1 GB this doesn't seem to be a good idea....

Using Php To Move Rows From Text File Into Mysql Table
Can anyone point me in the right direction for the way to read a text file a
line at a time and separate the fields on that line and use them as data in
an INSERT to add a record to a mysql table. Then read the second line in
text file and repeat.

Deleting Rows In Mysql
Is there a way in php that I can mark a row in my mysql database and then later so delete these rows that have been marked?

Deleting Mutiple Rows
I have this Code:

echo "<td>";
echo "<input type='checkbox' name='id' value='";
echo $row["id"];
echo "'></td>";
etc etc etc ect....

The above code works for 1 record at a time. I can't change the name of the form field to del[] cause I need that id in there.

Autoincrement - After Deleting Rows -
If I delete rows in my database via phpadmin, it remembers which row ID had previously been used, so the remaining records are 1, 3, 4, 5, 8 and the rows I deleted (2, 6, 7) no longer exist. Is there some means of having the database forget the dropped records, so the numbering is sequential?

Deleting Blank Rows
I have some rows in my mysql table that have blank fields as part numbers. I want to delete all of the rows that have blank part numbers.

would it be like:

delete from table where partnumber = '0';

Deleting Mysql Rows
Is there an easy or another way to delete rows? Right now I'm checkmarking the row I want to delete and then clicking on the red x for each one. It takes absolutely forever. Is there a better way?

Deleting Rows Across Multiple Tables
Using MySQL. Documentation is not clear to me, and it remains clear after doing some searching.

I know this does NOT work

DELETE FROM table1,table2,table3,table4 WHERE dataID='id'

Do I really need to run 4 queries? Seems awfully inefficient.

Mysql And Php5 Deleting Rows
I can't seem to delete rows from a mysql database. I have a database
that I want to delete rows from based on user name. i have researched
this extensively and can't seem to find anything that works.

Deleting Multiple Checked Rows With Foreach()
I'm trying to delete multiple entries from a mysql table using the following script:
variables are passed using: PHP Code:

Deleting Database Rows From An Array Of Variables
I have a form with a list of checkboxes, which are each filled with a date in the format 27012007, for example. The name of each of the checkboxes is the same as the date.

Basically when the user presses the submit button I would like all rows in the database table "users" with the corresponding column "date" to be deleted when the form variables date correspond to those in the "date" rows. I think all the checked dates might also need to be put into an array. Would anyone know how to do this?

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.

Editing And Deleting Flat Text Files
I am working on a php news script that uses text files for it's DB. I have most of it done except for the ability to edit or delete the articles in the DB.

I have only been coding for about a week now so my skills are pretty limited and I have not found any tutorials that cover this issue so if anyone could be kind enough as to show me how this is done I would be most greatful....

Deleting A File From Server Through A File List
I've been having trouble with this for a while. Ages ago I made an upload script that lets you upload to files/upload/ and then once you upload it, a piece of PHP will show the files in that folder.

In the admin section of my page i'm trying to find a way to delete the files off the server without having to dig into the FTP and do it manually.
Are you able to do that with PHP? Code:

Deleting Contents In File With PHP

Deleting A File A Short Time After
I have a feature on my site where a user chooses to download a
file, I create the file on a temp location on the server and allow the
user to download the file. I would like the file to be automatically
deleted after half an hour, but I'm a little unsure (and wonder if
it's possible) to do this with PHP.

I am running PHP 4 with Apache 1.27 web server running on Red Hat
Linux.

Deleting File(images) From Server
I want to be able to delete images I don’t use from my image directory on the server. Deleting images from my Mysql database goes well, but I can’t delete them from server directory. I use this simple function but even the path is right it doesn’t work. Code:

Deleting Lines From Flat File
I am trying to display all the news items in my flat file with 'delete' links (<a href="managedeletenews.php?action=delete&id=$key">Delete[/url]) that call the same page to strip out the line and rewrite the file.

However, when the delete link is clicked nothing happens (except the page's address changing from "managedeletenews.php" to the above.

Am I using the references to the $id or $key variables incorrectly?
Is it something to do with the undefined $action variable?
Or is it something else??
BTW, the embedded styles for the delete link - shown below - don't seem to be throwing up any errors. Code:

Deleting Session File From Server

Read And Display Japanese Text From Text File
I posted a question regarding reading japanese
text from a text file.

Well, since I solved the problem, I thought I'd post my solution for
the benefit of other people with the same problem.

The plan was to make a script to read and display japanese text. I
will use it for making a japanese proverb script and for a japanese
language study script.

Method :

I wrote a simple kanji text file (saved with UTF-8 encoding)
I wrote a simple PHP script to display the file contents (saved with
UTF-8
encoding)
I specified the content-type header for the HTML page :
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

*** All files have the same encoding. ***

UTF-8 supports japanese characters.

and it works!

this is my PHP (and HTML) script :

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>PHP : Japanese Text File Read : Exercise 1</title>
</head>
<body>

<?php

$filename="japanese.txt";
//open file
$fp = fopen($filename,'r');

//loop through each line in the file
while($line=fgets($fp))
{
//output current text file line
print $line."<br>";
}
//close file handle
fclose($fp);

?>

</body>
</html>

I know it's a very simple script, for testing purposes only. It
displays the contents of the japanese text file line by line.

The key was to save all files in the same encoding (I used UTF-8) and
to specify the encoding / charset in the HTML header (<meta
http-equiv="Content-Type" content="text/html; charset=utf-8">)

Count Amount Of Rows In Same Query Of Selecting Rows
I am selecting some rows from a table and i wonder if i can count
the amount of rows in that same table in the same query? I tried something like: PHP Code:

Remove Text Header In Text File
I have been having trouble removeing two header lines at the top of my txt file. You will see in my code the different things I have tried but with no luck. Below I posted my script and data.

Text Box To .txt File

Add Something To A Text File?
How would I go about adding a string on a new line at the end of a text file?

Text File Display
I have a number of SQL reports that create standard 132 column text files. The user wishes to view these files in a browser in addition to their daily printing on a laser printer.

I can handle directory structure, etc with PHP but I would like to know what is the best way of displaying these text files on screen. We can select them but they are very plain. Is there a TXT2HTML ot TXT2XML type tool that can display headings, bolding, etc without too much difficulty. I would rather not reprogram the reports as there are hundreds of them, and embedding HTML would not be an answer as they need to be printed on a regular laser.

Saving To A Text File.
I haven't been able to find a way to save the results of a MYsql query into a tab delimited text file... Anyone know how to do this, or if there are any already written scripts out there that perform this, or a similar function?

Database Row To Text File
I need to get the contents of a MySQL database field into a text file, and write the file to the server. I can not seem to get any filesystem functions to work, because it tells me I do not have permission to do anything. I am on virtual hosting, so it seems easier for me to try to FTP files to my own server.

Perhaps you guys can give me some pointers, this is kind of the idea I am running on:

Writing To A Text File

Write To A Text File Once Only
I've got a script that writes to a text file:

Text File Into Variable
I'm setting up an script that will send mail to an address given by a user. The problem is that the body of the e-mail varies depending on a few responses that the person gives, and writing out like 1000 lines of code just to get each of the outcomes covered is not my idea of fun. My question is, is there any way to make a variable in PHP the contents of a .txt file so I don't have to have that big of a script?

Retrieval From A Text File
How would I go about retrieving info from a text file into a variable field? If the data is stored in more than one line or separated by line breaks?

Php File Showing As Text
I have tried to upload a tested PHP file to my server and every time it gets
accessed it displays itself as text and does nothing that its supposed
to...

Form To Text File
I don't know anything about PHP, ASP, CGI, all I can do is use Microsoft FrontPage to edit html. But I have been searching the internet for a script (any laguage) that can send an html form to a text file. But I need the new data to replace existing data in the text file every time I submit new information.

Is this possible in PHP or any other language? I’m hosted on a UNIX server with php installed and I have access to my cgi-bin and all I need is this little script to complete my website.

Str_replace From Text File
I want to use a text file with words that needs to be replace. $theentry = str_replace(array('word1', 'word2'), '*****', $theentry); Instead of array('word1'),'word2') i want textfile.txt to be opened with all the words to be replace with ******.

Text File Instead Of Database?
Does anyone know a script that I can use to manage members of my website (preferably with a control panel-type interface) but without using a database? I read on hotscripts.com of one that uses text files instead, but the link says that the site is no longer offering that file.

If someone could help me it would be great, as I know nothing about scripting. By control panel, I mean a page that I can go to on my site (not open to the public) that I can use to Admin the users. I would like it to go something like this: (this is what was offered at hotscripts.com)

New Members Username:
New Members Password:
New Members Name:
New Members E-Mail Address:

And optionally (I don't really need it, but if its possible, hey why not) a place for me to put in an admin username and pass to get into the page mentioned above. I would also like to be able to implement this script on my main page (see here for what I mean.

Exploding Text File....
I want to put a text file into a form field, and then submit it to a page that will split up the text file on two criteria and then loop through each split result inserting new db records. A sample text file would be:

question 1;option1;option2l;option3

question 2;option1;option2l;option3

question 3;option1;option2l;option3

I need to split it on blank lines and then again on the options so that my insert would be insert questionname, option1, option 2....into questions. Can someone help please. I know I can use explode, but unless I am missing something then its just not working for me.

Get Data From Text File
I am trying to do is display the date like so: PHP Code:

Deleteing From A Text File?
Is there a function that deletes a line from a text file?

Exporting From Db To Text File
I have the following sql statement that works from phpmyadmin and from the MySQL command line, but not php. The resultant $sql variable is the following:

$sql=select logrecno, county, sumlev
into outfile "/tmp/census.txt"
fields terminated by ','
lines terminated by ""
from sf1_msageo
where sf1_msageo.county=97 and sf1_msageo.sumlev=140

$result=mysql_query($sql); The query executes, returns no messages, and does not create a file. Any idea as to what I'm doing wrong?

Get Date From Text/php-file
I'm new to PHP, and i want to create a pop-up (on page load) on certain dates..
What i have is the script for the pop-up:

<body scroll="auto" <?php $today =date("d-F"); if ($today==$datum)
{echo "onLoad=".$g_birthday_pop;}?>>

The pop-script =
$g_birthday_pop = <<<EOT
"MM_openBrWindow('http://www.nu.nl','popup','width=300,height=300')"
EOT;

$datum is in another file (include/datum.php):
<?php
$datum= "30-December";
?>

And this works if the date is 30th of December,
but i want it too on other dates that you put in $datum
Something like:
<?php
$datum= "30-December";"10-March";
?>
So i want to control the pop-up just by editing the "datum.php"-file

Comparing A Text File
I was wondering if this is possible: Compare a row from a table to a row from a text file, and if that row is not in that text file, then delete it from that table, and move it to another one. Say for example I read in a text file and assign the following variables: PHP Code:

Search A Text File
I have a text file that each line is an array, I think. I looks like this

name | id | # | # | # | total
name | id | # | # | # | total

and so on...

I would like to seach the file by "id" and only display the line with the particular "id".
I also think that the bit size of each line will change from line to line, so I don't think that I can put in a static number to search to the end of. I thought about using fseek(), is that the best way to go.

Php Generate Text File
I have been trying for the past 3-4 days now to get flash to write into a text file for me. Basically I made a rating script on flash and then I made another php file that counted the top 10. I want to get the info from the top 10 to a text file but I've been stuck for a while now.

I read php.net for the commands, kessler's tutorial, but I'm just missing something. I posted the top 10 script that works and the other that doesn't work when I try to text can someone please tell me what I'm messing up on? PHP Code:
