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

I hope that the below answer may be efficient and also simple:

$content = "The main string to search";
$search = "search";
//For compare the begining string with case insensitive. 
if(stripos($content, $search) === 0) echo 'Yes';
else echo 'No';

//For compare the begining string with case sensitive. 
if(strpos($content, $search) === 0) echo 'Yes';
else echo 'No';

//For compare the ending string with case insensitive. 
if(stripos(strrev($content), strrev($search)) === 0) echo 'Yes';
else echo 'No';

//For compare the ending string with case sensitive. 
if(strpos(strrev($content), strrev($search)) === 0) echo 'Yes';
else echo 'No';
