search in varaible/string function

Hello , can please tell me any name of built in function that returns true/or false on with given variable and findable string .. like strstr or substr etc. but they return a output but i want boolean value on return..

 

Just typecast the result as a bool:

echo (bool) stristr('mystring', 'str');

Code (markup):

PS "Beginner PHP Expert" Dude, wtf...

 

strpos will return a boolean false for not found, or an integer indicating the position.

if(strpos('...', $str) === false)

Code (markup):

$string = 'Hello world';
$needle = 'world';
$find = strpos($string, $needle) > 0;

 

No.

You must check for a boolean false using the strict-equality operator (===) in order to make it work with strpos. Unless you want it to miss it being the first word in the string.
