Getting values from associative array

Question

I have the following main array called $m

Array
(
    [0] => Array
        (
            [home] => Home
        )

    [1] => Arra         


        

Answer 1

Assuming keys in the sub arrays are unique you can

1. merge all sub arrays into a single array using call_user_func_array on array_merge
2. swap keys and values of your option array
3. Use array_intersect_key to retrieve an array with all the values.

Example like so:

$options = array('about_us', 'enquiry_form');

$values = array_intersect_key(
           call_user_func_array('array_merge', $m), // Merge all subarrays 
           array_flip($options)                     // Make values in options keys
          );  

print_r($values);

which results in:

Array
(
    [about_us] => About Us
    [enquiry_form] => Products
)
