[SOLVED] Link checker returns false

[The Swedish Tower]

What I'm trying to do is that I was to code a link checker.

It should sort out which url that belongs to the site and which that doesn't.

The problem is that it doesn't do that. It just returns all urls as false.

 

 

The valute of $url is

http://www.towerdefence.net

 

Code:

if (stristr($url , 'towerdefence.net')) {
check == "yes";
echo 'yesyesyyes';
}
else {
check == "no";
echo 'nonononon';
};

<?php
$url = "http://www.towerdefence.net";
if (stristr($url , 'towerdefence.net'))
{
$check = "yes"; //Added $ and removed a =
echo 'yesyesyyes';
}else {
$check = "no";//Added $ and removed a =
echo 'nonononon';
} //Removed a ;

?>
