Hi Ethan,
Is there a reason you're using shell commands to achieve the following:
<?php
$path = '/var/www/orders.txt';
if( !file_exists( $path ) )
{
if( !touch( $path ) )
{
echo 'Failed to touch file into existence: '.$path."\n";
}
else
{
if( !chmod( $path, 0766 ) )
{
echo 'Failed to update file permissions: '.$path."\n";
}
}
}
?>
Also, why are you setting the executable bit on a text file? :)
Cheers,
Rob.

When you say "does not work", can you show what is actually not working? I
believe the exec and system functions are likely working just fine, but that
the commands you've passed to them may not be.

Maybe you don't have write permissions on the folder?

echo exec('ls -la orders.txt');

Maybe you don't have write permissions on the folder?
If I perform the touch and chmod from the command line, everything works.

Here are my commands.
if( !file_exists("/var/www/orders.txt"));
{
echo system("touch /var/www/orders.txt", $ret);
echo system("chmod 766 /var/www/orders.txt", $ret);
echo 'file2<br />';
echo file_exists("/var/www/orders.txt");
}
If I now try a ls from the command line, the return is
cannot access /var/www/orders.txt: No such file or directory
The ls -la works because the file was created from the command line.
TIA
Ethan
