Hi all,

In PHP I just want to split a string, from a delimiter.

PHP

$str = "one/two/three";

$arr = explode('/', $str);

I just want to split this int to maximum arrays of two. So I can do it as follows.

PHP

$str = "one/two/three";

$arr = explode('/', $str, 2);

So the output will be,

one
two/three

But, I want to split it as,

one/two
three

How can I do that?

An alternative without array functions...

PHP

$last = strrpos($str, '/');
$left = substr($str, 0, $last);
$right = substr($str, $last+1);

I think you misunderstand the limit parameter off the explode[^] function. It is used to limit the number off element to be returned by the explode function and all remaining part are stored in the last string.

If you had used this

PHP

$str = 'one/two/three/four';
$arr = explode('/', $str, 2);

the result will be

one
two/three/four

and with this

PHP

$str = 'one/two/three/four';
$arr = explode('/', $str, 3);

the result will be

one
two
three/four

I found this How to Explode String Right to Left?[^] and based on it you can use:

PHP

$str = 'one/two/three';
$arr = array_map('strrev', explode('/', strrev($str), 2));

I have not tested it, so you need to see if it works.
