Remove lines with empty values from multidimensional-array in php

Question

How do you remove the lines that have empty elements from a multidimensional-array in PHP?

For instance, from:

1: a, b, c, d
2: d, _, b, a
3: a, b, _, _
         


        

Answer 1

I would iterate through a foreach loop myself something like:

 $array)
    {
        $empty_flag = false;

        foreach ($array as $key => $val)
        {
            if ($val == '')
            {
                $empty_flag = true;
            }
        }

        if ($empty_flag == true)
        {
            unset($md_array[$key]);
        }
    }
?>

There's almost definitely a more efficient way of doing this so anyone else who has a better solution feel free to let me and Alex know.
