What's the most efficient test of whether a PHP string ends with another string?

Question

The standard PHP way to test whether a string $str ends with a substring $test is:

$endsWith = substr( $str, -strlen( $test ) ) ==          


        

Answer 1

Another way would be to use the strrpos function:

strrpos($str, $test) == strlen($str) - strlen($test)

But that’s not faster.
