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

Don't know if this is fast or not but for a single character test, these work, too:

(array_pop(str_split($string)) === $test) ? true : false;
($string[strlen($string)-1] === $test) ? true : false;
(strrev($string)[0] === $test) ? true : false;
