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.


$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 !

your just looking in the string, if you want to look in the file you have to get its contents:

$active = file_get_contents("user_list.txt");

Good day to you all,
My code is looking for user name in a file, if match found, do nothing, if no match found, add to list.

Right now, it add anyway !



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

if ($pos === false) {

$output= $_SESSION['username']."\n";
$newfile="user_list.txt";
$file = fopen ($newfile, "a");
fwrite($file, $output);
fclose ($file); 


} else {


}

Thanks!

As dagon pointed out, your other thread (started today at 4:20 pm) was basically asking the same question as this thread (so I've merged the two).

Also, I might suggest that you instead load the file into an array of lines via [man]file/man and use [man]array_search/man to see if a username exists in the file.

Otherwise, simply using [man]strpos/man would return true if you searched for "Joe" and there was a username in the file called "JoeSmurf".

EDIT: Just to clarify, note that my suggestion above would necessitate the use of file()'s FILE_IGNORE_NEW_LINES flag for array_search() to work.
