Thank you

found this at php.net

I needed to append, but I needed to write on the file's beginning, and after some hours of effort this worked for me:
$file = "file.txt";
if (!file_exists("file.txt")) touch("file.txt");
$fh = fopen("file.txt", "r");
$fcontent = fread($fh, filesize("file.txt"));

$towrite = "$newcontent $fcontent";

$fh22 = fopen('file.txt', 'w+');
fwrite($fh2, $towrite);
fclose($fh);
fclose($fh2);

If you're using PHP 5, you can do the same type of thing like this...

<?php
$file_path = 'path_to/my_file.txt';

if ( is_file( $file_path ) ) {
  $contents = file_get_contents( $file_path );
  $modified = "ID Category Description\n$contents";
  file_put_contents( $file_path, modified );
} else {
  die( "File does not exist at this location: $file_path" );
}
?>

Please change $file_path value to the path to your specific file...

Hope this helps.

Is petsfeed.txt on a server? Check it's read-write permissions.
Are you getting any error message, if so, please post it here.

<?php
$file_path = 'path_to/my_file.txt';

if ( is_file( $file_path ) ) {
  if ( is_readable( $file_path ) && is_writable( $file_path ) ) {
    $contents = file_get_contents( $file_path );
    $modified = "ID Category Description\n$contents";
    file_put_contents( $file_path, modified );
  } else {
    die( "Please change the read-write permissions of this file: $file_path" );
  }
} else {
  die( "File does not exist at this location: $file_path" );
}
?>

Using this code :
error_reporting(E_ALL ^ E_NOTICE);
ini_set("display_errors", true);


$file = "petsfeed.txt";
  
      if (!file_exists("petsfeed.txt")) touch("petsfeed.txt");
  
      $fh = fopen("petsfeed.txt", "r");
  
      $fcontent = fread($fh, filesize("petsfeed.txt"));
 
      $towrite = "ID Category    Description";

       

      $fh22 = fopen('file.txt', 'w+');

      fwrite($fh2, $towrite);
 
      fclose($fh);
 
      fclose($fh2);
I get this error

Warning: fwrite(): supplied argument is not a valid stream resource in /var/www/html/yumasun/media/gadzoo/txt.php on line 21
Warning: fclose(): supplied argument is not a valid stream resource in /var/www/html/yumasun/media/gadzoo/txt.php on line 25

Sorry, that was a bad example
on this line $fh22 = fopen('file.txt', 'w+'); is using the variable $fh22 and the next two lines need to use that variable instead of $fh2 write($fh2, $towrite); fclose($fh2); Sometimes what other people post is not always correct, even(especially) on php.net.

Not for me, I copied that script, refreshed my page about 7 or 8 times and got this in pets_feed_20080829.txt

ID Category Description
ID Category Description
ID Category Description
ID Category Description
ID Category Description
ID Category Description
ID Category Description
ID Category Description
ID Category Description

which means that it is working fine.

It is on a server and no is not giving me any error message is just not writting anything to the file

langsor · Answer 4 · 2008-08-28T02:47:53+00:00

Hmmn, maybe the error message is not going to the browser but going to a log or turned off.

What version of PHP is on the server, because my script example requires PHP 5 or newer, but if PHP could not find the functions I'm using it would put out an error ...

How are you calling this PHP script. Are you loading it in the browser location bar? If so it should work.

I would post a file that you know will give you an error message and load that in the browser to see that you're getting error messages.

error.php

<?php
require 'foobar';
?>

should give you this error message:

Warning: require(foobar) [function.require]: failed to open stream: No such file or directory in C:\Documents and Settings\Creative\My Documents\Server\public\admin.loomba\error.php on line 3

Fatal error: require() [function.require]: Failed opening required 'foobar' (include_path='.;..;../..;../../..') in C:\Documents and Settings\Creative\My Documents\Server\public\admin.loomba\error.php on line 3

If you have access to your php.ini file you can search for 'error' and see what the settings are too.

Good luck

I am loding in it on the browser I am not getting an error but still is not writting

to the file

error_reporting(E_ALL ^ E_NOTICE);
ini_set("display_errors", true);


$file = "petsfeed.txt";
  
      if (!file_exists("petsfeed.txt")) touch("petsfeed.txt");
  
      $fh = fopen("petsfeed.txt", "r");
  
      $fcontent = fread($fh, filesize("petsfeed.txt"));
 
      $towrite = "ID Category    Description";

       

      $fh22 = fopen('file.txt', 'w+');

      fwrite($fh22, $towrite);

Made some adjustments, this works fine for me.

<?
error_reporting(E_ALL ^ E_NOTICE);
ini_set("display_errors", true);


$file = "petsfeed.txt";
  
if (!file_exists("petsfeed.txt")) touch("petsfeed.txt");

$fh = fopen("petsfeed.txt", "r");

$fcontent = fread($fh, filesize("petsfeed.txt"));

$towrite = "ID Category    Description";



$fh22 = fopen('petsfeed.txt', 'w+');

fwrite($fh22, $towrite . $fcontent);

fclose($fh);

fclose($fh22);
?>

You will have to use "\n" for new lines of course as this is just writing to one line.

Yes, the way the script works is if the file does not exist, it will be created automatically.

Your getting that because the file was just created so file size = 0. This doesn't mean it's not working it's just letting you know that fread won't read anything because there is nothing to read yet. Let me make one adjustment.

This should clear that up.
