Create an assoc array with equal keys and values from a regular array

Question

I have an array that looks like

$numbers = array('first', 'second', 'third'); 

I want to have a function that will take this array as input and return an array that would look like:

array( 'first' => 'first', 'second' => 'second', 'third' => 'third' ) 

I wonder if it is possible to use array_walk_recursive or something similar...

Answer 1

You can use the array_combine function, like so:

$numbers = array('first', 'second', 'third'); $result = array_combine($numbers, $numbers);
