rtrim anything starting with a specific set of characters

Question

Sorry I don't have any code to post to be discussed, it's one simple question

How to rtrim a string beginning from a set of characters?

String: abcdefghijk

What to remove: fghijk

Anything at the end of the string that starts (the part to be removed) with fg

So, if we have dpgjsufgpeiz, remove fgpeiz

Thanks!

If TRUE, strstr() returns the part of the haystack before the first occurrence of the needle (excluding the needle).

$whatwewant = strstr($input, 'fg', true);

You can simply use preg_replace to achieve the desired output:

$output = preg_replace('/fghijk$/s', '', 'abcdefghijk');

You can always use preg_replace

$str = 'dpgjsufgpeiz'
$str = preg_replace('/fg\w*$/', '', $str);
