A better php array_merge

Question

I am looking to do this a better way without the need to hardcode the integers for $justPrices[$i]:

$pricesResult = array_merge($justPrices[0],          


        

Answer 1

If you just want to flatten the array, you can use call_user_func_array to call array_merge with the elements of $justPrices as parameters:

$flat = call_user_func_array('array_merge', $justPrices);

This is equivalent to a the function call:

$flat = array_merge($justPrices[0], $justPrices[1], … , $justPrices[count($justPrices)-1]);
