How do I return all the values in an array?

Sometimes the relationship between the key and the value in an array will be of importance to us, but often that is not the case and all we really want to concentrate on are the values in the array.

For times like this, PHP provides us with the array_values function, which will simply return is an array containing the values, like so:


<?php

$example = array(572=>"i","don't","care","much","for","keys");

print_r($example);

$values = array_values($example);

print_r($values);

?>

Which prints:

Array
(
[572] => i
[573] => don't
[574] => care
[575] => much
[576] => for
[577] => keys
)
Array
(
[0] => i
[1] => don't
[2] => care
[3] => much
[4] => for
[5] => keys
)

You can see that the keys from the initial array are gone, but if we weren't interested in those then that's just fine!
