Answer 1

From the manual:

This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE, such as 0 or "". Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.

In your example, you should use

$string = "123";
$search = "123";

if ( false !== strpos( $string, $search ) ) {
    echo "found";
} else {
    echo "not found";
}
