Fetching the first word of a string using php

Question

I want to split a string into two variables, the first word and the rest of the string. The first word will be only one of four different words.

$string = explode (' ', $string, 2);
$word = $string[0];
$string = $string[1];

The above seems to work, but I wonder if there is a better way.

Answer 1

You can use list():

list($word, $string) = explode (' ', $string, 2);

But this is already good. In this case, regular expressions will be redundant.

Answer 2

There are many ways to do this. Using regular expressions, using strtok()etc. Using explode()how you do is good.

Answer 3

list($word, $string) = explode(' ', $a, 2);
