Multidimensional Associative Array (PHP)

Question

I\'m new to arrays in PHP and am trying to wrap my mind around how to make a multidimensional associative array. I\'d like the array to look like this when I use print_r:

Answer 1

$alert_array = array();
$alert_array[] = array('alert' => 'alert', 'email' => 'Test');
...
var_dump($alert_array);

In your case you'd have to specify key like so:

$alert_array[$key]["alert"] = "alert";
$alert_array[$key]["email"] = "Test";

You'd have to have a loop with counter too.

If you're using PHP 5.4+ you could use short array syntax:

$alert_array = [];
$alert_array[] = ['alert' => 'alert', 'email' => 'Test'];

Answer 2

if you put an already existing Array inside a new Array using array function , then your result will be multi-dimensional array

    $alert_array = array();
    $alert_array[] = array('alert' => 'alert', 'email' => 'Test');
    print_r($alert_array);

    /* result will be
    Array ( [0] => Array ( [alert] => alert [email] => Test ) )
    */

In this case, result will be one-dimensional array

$alert_array = array();
while($variable = mysqli_fetch_assoc($something)) {
$alert_array[] = $variable;
}
