You can't compare strings/hashes in PHP with just the equality operator (==), you need to check that the 2 strings/parts are identical (see http://php.net/manual/en/language.operators.comparison.php). This problem is actually very widespread and some blogs/articles deal with it e.g. (just one randomly picked page that explains this problem) https://www.whitehatsec.com/blog/magic-hashes/
