Solution:
An array whose values are empty strings is not the same asNULL. You need to test the values.
You can callarray_filter() on the element. This will return all the non-empty values in the array; if all the values are empty it will return an empty array, which will be condidered falsey by the outerarray_filter().
$filtered = array_filter($myArray, function($var){return array_filter($var);} );
Or you could just check whether a specific element such aspost_id is empty:
$filtered = array_filter($myArray, function($var){return !empty($var['post_id']);} );
