Find last character in a string in PHP

A nice solution to remove safely the last / is to use

$string = rtrim($string, '/');

rtrim() removes all /s on the right side of the string when there is one or more.

You can also safely add exactly one single / at the end of an URL:

$string = rtrim($string, '/').'/';

You can use substr:

substr($str, -1)

This returns the last byte/character in a single-byte string. See also the multi-byte string variant mb_substr.

But if you just want to remove any trailing slashes, rtrim is probably the best solution.

And since you’re working with URLs, you might also take a look at parse_url to parse URLs as a trailing slash does not need to be part of the URL path.

$string[strlen($string)-1] gives you the last character.

But if you want to strip trailing slashes, you can do $string = rtrim($string, '/');. If there is no trailing slash, $string will remain unchanged.
