How to check the sub string is exists or not in main string

Is there any way to check the sub string is exists in main string or not. If exits, no need any another action. If not exists, I want to add some another string to main string.

For an example:

$a = 'Hello world';
$b = 'Hello';

I want to check the $b is exists in $a or not. If exists, i am sending that variable to database. If not exists, I want to use str_replace('Hello', $b.'World', $b).

if (strpos($a, $b) !== false) {
    // $b is in $a
} else {
    // $b is not in $a
    str_replace('Hello', $b . 'World', $b);
}

You are looking for strpos function

remember to use === instead of ==

strpos().

It returns FALSE if the substring is not found.
