Split into two variables?

Question

Say I have the following: "44-xkIolspO"

I want to return 2 variables:

$one = "44";
$two = "xkIolspO";

What would be the best way to do this?

Remember, the manual lists every function you could ever want: http://php.net/ref.strings — Jonah, Jan 19 '11 at 03:17
Well, unless you know how many variables you must get, `list()` may render quite useless. Manual assignment is better. In such cases, use a `foreach()` to create an array of values. — Fr0zenFyr, Apr 11 '19 at 05:56

Try this:

~~list($one, $two) = split("-", "44-xkIolspO", 2);~~

list($one, $two) = explode("-", "44-xkIolspO", 2);

Awesome, except that [split is deprecated](http://php.net/manual/en/function.split.php). A more future-proof solution would probably be [explode](http://php.net/manual/en/function.explode.php). – sdleihssirhc Jan 19 '11 at 03:05
use preg_split("/-/", "44-xkIolspO"); – Mihai Toader Jan 19 '11 at 03:07

Updated the post to use explode. Hope its not deprecated yet. – Chandu Jan 19 '11 at 03:07

According to http://micro-optimization.com/explode-vs-preg_split using preg_split is 69% faster. – Mike Kormendy Nov 06 '14 at 22:37

@MikeKormendy when you read the article it says "f2 is slower than f1 by 68.73% " where f2 is the preg_split and f1 is the explode. So, unless I'm missing something obvious, the article is saying that explode is 69% fater than preg_split – philip May 22 '17 at 18:16

PHP has a function called preg_split() splits a string using a regular expression. This should do what you want.

Or explode() might be easier.

    $str = "44-xkIolspO";
    $parts = explode("-", $str);
    $one = $parts[0];
    $two = $parts[1];

I don't think preg_split is anywhere near necessary in this case. Regular expression parsing is much less efficient than a delimiter string. – Jonah Jan 19 '11 at 03:15
