php - Check if website is in the blocked list -

am creating class handles redirection exterior locations. created method called isblocked returns boolean result. function works follows:

it loops through $_blocked variable , compares input string found, it returns true otherwise false. bellow actual incase explanation not enough.

public static function isblocked($location) {      for($i = 0; $i < sizeof(self::$_blocked); $i++)      {          if(self::$_blocked[$i] === $location)          {              return true;          }          else           {              return false;           }      } } 

this works perfectly, problem comes when example, lets "google.com" on list , input "www.google.com", return false. obvious since using identical operator ===.

question following: there function in php work urls apart url_encode & url_decode? can create regular expression let me know if there other approach this.

thanks in advance.

it occurs me match backwards, since it's many one, 1 matching (sub)part of in stack. so, in case can use strpos() (in lieu of regular expression):

function find_reverse_match($needle, $haystack) {     $i = 0;     $c = count($haystack);      while ($i < $c) {         if (strpos($needle, $haystack[$i++]) !== false) {             return true;         }     }      return false; }
