How to get the last char of a string in PHP?

Question

I need to get the last character of a string. Say I have \"testers\" as input string and I want the result to be \"s\". how can I do that in PHP?

Answer 1

I can't leave comments, but in regard to FastTrack's answer, also remember that the line ending may be only single character. I would suggest

substr(trim($string), -1)

EDIT: My code below was edited by someone, making it not do what I indicated. I have restored my original code and changed the wording to make it more clear.

trim (or rtrim) will remove all whitespace, so if you do need to check for a space, tab, or other whitespace, manually replace the various line endings first:

$order = array("\r\n", "\n", "\r");
$string = str_replace($order, '', $string);
$lastchar = substr($string, -1);
