    • This is how you do it with regex: 

    $needle = "/this/";
echo preg_match($needle, $haystack);


    This will return 1 one if it matches else 0

    You don't need regex to do this. As already mentioned in comments use strpos(): 

    if(strpos($heystack, $needle) !== false) {
// contains
}

    尝试这个： 

    $haystack = "451516178jjgsjkjjssbbziznbdkbnjv.bvkljk_isikjsksjkthisjkhkjhkjh4364765467";
$needle = "this";

$string = strpos($haystack, $needle);

if($string === false)
 echo "false";
else
 echo "true";
