字符串函数中的Php字符串

Posted 2021-02-27

// php has no "in_string" function, so here's one...
 
function in_string($needle, $haystack, $insensitive = 0) {
if ($insensitive) {
		return (false !== stristr($haystack, $needle)) ? true : false;
	} else {
		return (false !== strpos($haystack, $needle))  ? true : false;
	}
}
