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

I adopted the answer from @Darkwaltz4 for its brevity and would like to share how I adapted the solution to situations where the array may contain different keys for each iteration like so:

Array[0] ...
['dob'] = '12/08/1986';
['some_key'] = 'some value';

Array[1] ...
['dob'] = '12/08/1986';

Array[2] ...
['dob'] = '12/08/1986';
['some_key'] = 'some other value';

and maintained a "master key" like so:

$master_key = array( 'dob' => ' ' ,  'some_key' => ' ' );

array_merge would have executed the merge in the Array[1] iteration based on $master_key and produced ['some_key'] = '', an empty value, for that iteration. Hence, array_intersect_key was used to modify $master_key in each iterations like so:

foreach ($customer as $customer) {
  $modified_key = array_intersect_key($master_key, $unordered_array);
  $properOrderedArray = array_merge($modified_key, $customer);
}
