How to remove empty values from multidimensional array in PHP?

Question

I\'ve been looking a lot of answers, but none of them are working for me.

This is the data assigned to my $quantities array:

Array(
             


        

Answer 1

The following function worked for my case. We can use a simple recursive function to remove all empty elements from the multidimensional PHP array:

function array_filter_recursive($input){
    foreach ($input as &$value){
        if (is_array($value)){
            $value = array_filter_recursive($value);
        }
    }
    return array_filter($input);
}

Then we just need to call this function:

$myArray = array_filter_recursive($myArray);
