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

As of PHP 7.1.0, negative string offsets are also supported. So, if you keep up with the times, you can access the last character in the string like this:

$str[-1]

At the request of a @mickmackusa, I supplement my answer with possible ways of application:

 string(1) "e"

$str[-3]='.';
var_dump($str);     // => string(6) "abc.ef"

var_dump(isset($str[-4]));  // => bool(true)

var_dump(isset($str[-10])); // => bool(false)
