PHP preg_match for url

Question

$request = '/test.php?action=save&key=e7s2uHhKKtcM32cHKUKM&login=test';
$param = preg_match("#^test.php?action=save&key=(\w+)&login=(\w+)($)#", $request, $match);
print_r($param);

It's not working. How to fix?

Answer 1

1. You need to escape your preg control characters "." and "?"
2. You are matching ^test meaning the string should start with "test", while your string starts with "/test"

3. I highly recommend to use single ticks so you don't have to escape your escape characters "\".

   $param = preg_match('#^/test\.php\?action=save&key=(\w+)&login=(\w+)($)#', $request, $match);
   print_r($param); // 1
   print_r($match); // Array (
   // (
   //     [0] => /test.php?action=save&key=e7s2uHhKKtcM32cHKUKM&login=test
   //     [1] => e7s2uHhKKtcM32cHKUKM
   //     [2] => test
   //     [3] => 
   // )
