Popping the key & value from an associative array in PHP

Question

Let S be an associative array in PHP, I need to retrieve and extract from it the first element, both the value and the key.

I would use

value1=array_pop         


        

Answer 1

array_slice

$arr = array('k1' => 'v1', 'k2' => 'v2', 'k3' => 'v3');

$a = array_slice($arr, 0, 1);
var_dump($a);

$arr = array_slice($arr, 1);
var_dump($arr);


array(1) {
  ["k1"]=>
  string(2) "v1"
}
array(2) {
  ["k2"]=>
  string(2) "v2"
  ["k3"]=>
  string(2) "v3"
}
