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

$endsWith = substr_compare( $str, $test, -strlen( $test ) ) === 0

Negative offset "starts counting from the end of the string".
