[RESOLVED] Php Replace From File

[shark4102]

Hi, I have this code:

$iii = 'uonline/online_users.txt';
$user = $_SESSION['user_name'].'<br>';
$mcon = file_get_contents($iii);
str_replace($user,"",$mcon);
file_put_contents($iii, $mcon);

I am TRYING to delete $user from the file $iii.

Example:

online_users.txt Contains:

Matt<br>Ashley<br>Sally<br>Jason<br>Mike<br>

The persons username is Ashley, So It should find 'Ashley<br>' in the file and delete it:

online_users NOW Contains:

Matt<br>Sally<br>Jason<br>Mike<br>

How can I do this?? Please Help Me!
-Thanks!

I fixed it! I just had to pull file contents into a Variable, then use substr to replace it with "" and send that to the file, sweet, thanks anyways!!

Note in your original code, the only real problem I see was this:

str_replace($user,"",$mcon);

Since [man]str_replace/man returns the new string, and since you never did anything with that returned value, that line isn't doing anything at all.
