PHP adressing the first key in an array that changes

Question

For example, lets say I have an array that looks liked

$stuff = array('random_string_1' => 'random_value_1','random_string_2' => 'random_value_2');

and then I call the asort() function and it changes the array around. How do I get the new first string without knowing what it actually is?

This, `echo $stuff[key($stuff)];`. Here's the doc, [http://php.net/manual/en/function.key.php](http://php.net/manual/en/function.key.php) — Rajdeep Paul, Dec 23 '16 at 22:32

If you want to get the first value of the array you can use reset

reset($stuff);

If you want to also get the key use key

key($stuff);

If you need to get the first value, do it like this:

$stuff = array('random_string_1' => 'random_value_1','random_string_2' => 'random_value_2');

$values = array_values($stuff); // this is a consequential array with values in the order of the original array

var_dump($values[0]); // get first value..
var_dump($values[1]); // get second value..
