Match $var in text file ?

[Peuplarchie]

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 using strpos incorrectly. The first argument is a string. Giving a filename doesn't make it magically open the file. You'll need to take a look at fopen, fgets (or fread), or maybe others (file, file_get_contents, et cetera).
