The usual practice when checking for the return value of functions is to run the function and store the value in a variable, and then test that variable. Here is an example of that process using the strstr() function.

$string = 'abcde';
$var = strstr($string, 'f');
if ( false !==  $var ) {
    var_dump($var);
} else {
