Php Simple method to determine whether a string contains another string, PHP string

This article describes a simple way for PHP to determine whether a string contains another string. Share to everyone for your reference, as follows:

When using PHP to determine if a string contains a simple substring, we usually use Strpos () or stristr (), but it happens that if the position of the string is at index 0, that is, at the beginning of the string to be matched, there will be a problem.

Of course, we still have a solution, there is a stupid way, but more useful, both in English, punctuation is applicable.

The code is as follows:

function Checkstr ($STR, $target) {  $TMPARR = explode ($str, $target);  Print_r ($TMPARR);  if (count ($TMPARR) >1) return true;  else return false;} $result = Checkstr ("SDFG", "BSDFSLDKFJ"); Var_dump ($result);
