Trying to write to a text file

nick1

Greetings,

I'm using Ubuntu Linux v5.10, Apache2, and PHP5.
I am the only user of the computer.

/etc/apache2/sites-available/default.txt is configured to use /var/www/testdir/ as the document root.
I am simply trying to write to a text file located in /var/www/testdir/test.txt

/var/www/testdir/ contains: test.txt and test.php

Here is my PHP script:

<?php

  $testfile = "/var/www/testdir/test.txt";
  $filehandle = fopen($testfile, "w");

  $stringData = "Write this stuff to file\n";
  fwrite($filehandle, $stringData);

  $stringData = "Then write this stuff to file too\n";
  fwrite($filehandle, $stringData);

  fclose($filehandle);

?>

Here is the error being returned after the PHP script is ran:

Warning: fopen(/var/www/testdir/test.txt) [function.fopen]: failed to open stream: Permission denied in /var/www/testdir/test.php on line 4

Warning: fwrite(): supplied argument is not a valid stream resource in /var/www/testdir/test.php on line 7

Warning: fwrite(): supplied argument is not a valid stream resource in /var/www/testdir/test.php on line 10

Warning: fclose(): supplied argument is not a valid stream resource in /var/www/testdir/test.php on line 12

I have a feeling this has to do with file permissions and unfortunately I'm a bit of a newbie to Linux. I have not changed any directory or file permissions so they should all be set to the default. I am the only user of this computer.

Any suggestions on getting this to work would be very much appreciated.

Thank you for your time,

Nick

Not a linux user, but have you tried to write to the file relative to the location of the script. ie try writing to the file one folder below the site.
/script.php
/testdir/

$testfile = "testdir/test.txt";

Changing the way you get to the directory isn't going to change the fact that there's a permissions problem (as stated in the PHP error message).

Most Unix setups have the Apache httpd service running as the 'nobody' user. Try CHMOD'ing the testdir directory to 775. If that doesn't work, try CHMOD'ing it to 777.
