PHP: checking problem

[unbound]

Hey! I've been working on this little chat thingy in php and got a problem now.
I have a textfile which has some text, like this:
a
b
c
d
e

every letter on its own row, and php code:

$all = file(myfile.txt);
	
// do the checking
for($i = 0; $i < count($all); $i++) {
 if($all[$i] == "b") {
     die("for good");
 }
}

but $all[$i] doesnt equal to b, eventhough it exists in file. So, what should I do to make it work?
Thanks in advance.

<?php

$file = implode('', file('mylist.txt'));

for($i = 0; $i < strlen($file); $i++) {
	if($file[$i] == "b"){
		die("for good.");
	}
}

?>

That does what you are asking, but what are you trying to accomplish, just wondering ?

http://www.php.net/file
http://www.php.net/strlen
http://www.php.net/implode

Good luck,

use trim to remove the newline.
if (trim($all[$i]) == "b") {

Thanks for your answers, got it working now.
What i'm trying to accomplish? I have this system that when user joins chat he writes hes name in a box and after that this script checks if it is already in use.
