split at the first space in a string

Question

I have a string like this:

red yellow blue

and I want to get an array like this :

Array ( [0] => red [1] => yellow blue )

how to split at the first space in a string ? my code doesn't work

<?php $str = "red yellow blue"; $preg = preg_split("/^\s+/", $str); print_r($preg); ?> 

please help me.

Answer 1

Use explode with a limit:

$array = explode(' ', $string, 2); 

Just a side note: the 3rd argument of preg_split is the same as the one for explode, so you could write your code like this as well:

$array = preg_split('#\s+#', $string, 2);
