6 gru 2010 · In PHP, the best way to verify if a string contains a certain substring, is to use a simple helper function like this: function contains($haystack, $needle, $caseSensitive = false) { return $caseSensitive ? (strpos($haystack, $needle) === FALSE ? FALSE : TRUE): (stripos($haystack, $needle) === FALSE ? FALSE : TRUE); } Explanation:
You can use strpos() or stripos() to check if the string contain the given needle. It will return the position where it was found, otherwise will return FALSE. Use the operators === or `!== to differ FALSE from 0 in PHP.
This function will check if a string contains a needle. It _will_ work with arrays and multidimensional arrays (I've tried with a > 16 dimensional array and had no problem). <?php function str_contains ($haystack, $needles) {//If needles is an array if(is_array ($needles)) {//go trough all the elements foreach($needles as $needle)
