Stop explode after certain index

Question

How can I stop explode function after certain index. For example

Answer 1

You could read the documentation for explode:

$result = explode(" ", $test, 10);

Answer 2

What's about that third parameter of the function?

array explode ( string $delimiter , string $string [, int $limit ] )

check out the $limit parameter.

Manual: http://php.net/manual/en/function.explode.php

An example from the manual:

<?php
$str = 'one|two|three|four';

// positive limit
print_r(explode('|', $str, 2));

// negative limit (since PHP 5.1)
print_r(explode('|', $str, -1));
?>

The above example will output:

Array ( [0] => one [1] => two|three|four ) Array ( [0] => one [1] => two [2] => three )

In your case:

print_r(explode(" " , $test , 10));

According to the php manual , when you're using the limit parameter:

If limit is set and positive, the returned array will contain a maximum of limit elements with the last element containing the rest of string.

Therefore , you need to get rid of the last element in the array. You can do it easily with array_pop (http://php.net/manual/en/function.array-pop.php).

$result = explode(" " , $test , 10);
array_pop($result);
