Sort an Array by keys based on another Array?

Question

Is it possible in PHP to do something like this? How would you go about writing a function? Here is an example. The order is the most important thing.

$custo         


        

Answer 1

A bit late, but I couldn't find the way I implemented it, this version needs closure, php>=5.3, but could be altered not to:

$customer['address'] = '123 fake st';
$customer['name'] = 'Tim';
$customer['dob'] = '12/08/1986';
$customer['dontSortMe'] = 'this value doesnt need to be sorted';

$order = array('name', 'dob', 'address');

$keys= array_flip($order);
uksort($customer, function($a, $b)use($keys){
    return $keys[$a] - $keys[$b];
});
print_r($customer);

Of course 'dontSortMe' needs to be sorted out, and may appear first in the example
