Split a string on the last occurring space

Question

I need to split a string into two parts. The string contains words separated by a space and can contain any number of words, e.g:

$string = "one two three four five";

The first part needs to contain all of the words except for the last word.

The second part needs to contain just the last word.

EDIT: The two parts need to be returned as strings, not arrays, e.g:

$part1 = "one two three four";

$part2 = "five";

Answer 1

Use strrpos to get last space character's position, then substr to divide the string with that position.

<?php
    $string = 'one two three four five';
    $pos = strrpos($string, ' ');
    $first = substr($string, 0, $pos);
    $second = substr($string, $pos + 1);
    var_dump($first, $second);
?>
