Good day to you all,
stupid as it sound, all the thing that I have tried to match a variable into a text file and execute according to it result.

PHP Code:

$active = "user_list.txt";
$pos = strpos($active, $_SESSION['username']);
if ($pos === false) {
echo "<b id=\"userinfo\"><img src=\"enligne.png\" valign=\"bottom\" width=\"13px\"/></b>";
} else {
echo "<b id=\"userinfo\"><img src=\"horsligne.png\" valign=\"bottom\" width=\"13px\"/></b>";
} 

Thanks !

You're matching it against the file name. You need to get the actual contents of the file: PHP: file_get_contents - Manual

Thanks, I knew it was a stupid thing I was not seeing cause of the level of sleep I had last night !

Can I delete it too ?

Read the file contents with file_get_contents().
Replace the name with nothing, using str_replace().
Put the contents back to the file using file_put_contents().

[=OTS=G-Man]

should be something like

PHP Code:

<?
$activeadmlist = "user_list.txt";
$current = file_get_contents($activeadmlist);
$pos = strpos($current, $_SESSION['username']);

if ($pos === false)
{
    $current .= $_SESSION['username']."\n";
    file_put_contents($activeadmlist, $current);
}
else
{
    //TODO:: do someting
}  

?>

used the code flow from your duplicate post

untested, but should work
