getting all the values in an array except the last one

I have this right now : 

$s = preg_split('/\s+/', $q);
    $k = end($s);

What I want now is to get all the values in the array $k[] except the last one, and join them in a new string. So basically if the array was :

0 => Hello
1 => World
2 => text

I would get Hello World

Use array_slice and implode:

$k = array( "Hello", "World", "text" );
$sliced = array_slice($k, 0, -1); // array ( "Hello", "World" )
$string = implode(" ", $sliced);  // "Hello World";

If you can modify the array:

array_pop($k);
$string = join(' ', $k);

array_pop() pops and returns the last value of the array, shortening the array by one element. If array is empty (or is not an array), NULL will be returned.

Something like this:

<?php

    $array = array('Hello', 'World', 'text');
    $new_array = array_slice($array,0,-1);
    echo implode(' ',$new_array);

?>

Use array_slice($array) to get a subset of any array.

For everything without the last item I believe it is

$return = array_slice($array, 0, count($array)-1, true);
