PHP add elements to multidimensional array with array_push

Question

I have a multidimensional array $md_array and I want to add more elements to the sub-arrays recipe_type and cuisine coming from a loop that reads data from a table.

Answer 1

As in the multi-dimensional array an entry is another array, specify the index of that value to array_push:

array_push($md_array['recipe_type'], $newdata);
