array_pop() with Key

Question

Consider the following array

$array = array('fruit'     => 'apple',                'vegetable' => 'potato',                'dairy'     => 'cheese'); 

I wanted to use array_pop to get the last key/value pair.

However, one will note that after the following

$last = array_pop($array);  var_dump($last); 

It will output only the value (string(6) "cheese")

How can I "pop" the last pair from the array, preserving the key/value array structure?

Answer 1

Check out array_slice() http://php.net/manual/en/function.array-slice.php

Last argument true is to preserve keys.

When you pass the offset as negative, it starts from the end. It's a nice trick to get last elements without counting the total.

$array = [     "a" => 1,     "b" => 2,     "c" => 3, ];  $lastElementWithKey = array_slice($array, -1, 1, true);  print_r($lastElementWithKey); 

Outputs:

Array (     [c] => 3 ) 

Answer 2

try

end($array); //pointer to end each($array); //get pair
