[Resolved] File Editing Problem

[kenhess]

Here is my code:

$line = file("/opt/apps/$PROJECT");
foreach($line as $k => $v) {
if(strpos($v, $username)) {
unset($line[$k]);
}
}
$file = fopen("/opt/apps/$PROJECT","w+");
fwrite($file, implode("",$line));
fclose($file);

The file $PROJECT has the format of:

name:application
name2:application

and $username is selected from a form which corresponds to name, name2, etc.

I am trying to remove a username from the file with this code, but it won't work. No php errors either, just doesn't work and the app does have access to the file because the other form writes the name to the file.

[man]strpos[/man] returns the position where the needle occurs in the haystack and that position could be (and in your case is) at position 0. in PHP 0 evalutes to boolean FALSE, so your expression will return false even though the string is there. you need to explicilty test for boolean TRUE:

if (strpos($v, $username) !== false) {...
