How to sort and implode an array

Question

I have an array from a database select query that looks like this;

Array ( [0] => Array ( [0] => Array ( [users] => Array ( [email] => [email protected] ) ) [1] => Array ( [users] => Array ( [email] => [email protected] ) ) ) )

How do I just get the email addresses so that it looks like this:

[email protected], [email protected]

Your database can most likely do what you want; do you need to sort and implode in PHP, or would sorting/imploding in the database (and returning that to PHP) be okay for you? — salathe

I've recreated you array structure for this example. I hope this will get you started.

<?php
    $all = array(
        array(
            array('users' => array('email' => '[email protected]')),
            array('users' => array('email' => '[email protected]'))
            )
        );
    $cleanarray = array();
    foreach ($all[0] as $key => $value) {
        array_push($cleanarray, $value['users']['email']);
    }
    $comma_separated = implode(",", $cleanarray);
    echo $comma_separated;
?>

If you're just looking for a recursive array search there is one built into PHP now.

function itemTest_func($item,$key){
     if($key == 'email') array_push($item);
}

array_walk_recursive($Multi_level_array, 'itemTest_func');
