Problem with rtrim function

Description

The following code:

<?php

echo rtrim("array_find.md", ".md");

// Output: array_fin

But I expected this output instead:

// expect output: array_find

PHP Version

php 8.4

Operating System

macos 14

https://www.php.net/manual/en/function.rtrim.php strips characters, so the d is striped twice because it is after the . in the string when stripping from the right.

Look at https://www.php.net/manual/en/function.pathinfo.php if you want to strip the extension
