How to get the first item from an associative PHP array?

Question

If I had an array like:

$array[\'foo\'] = 400;
$array[\'bar\'] = \'xyz\';

And I wanted to get the first item out of that array without knowing

Answer 1

I do this to get the first and last value. This works with more values too.

$a = array(
    'foo' => 400,
    'bar' => 'xyz',
);
$first = current($a);   //400
$last = end($a);    //xyz
