php - How do I convert an object to an array? - Stack Overflow
I use this approach to convert an array of PHP objects to an array of associative arrays. You need to do this in Laravel 5 when you query database rows not using an Eloquent Model facade but the DB facade.

python - NumPy array/matrix of mixed types - Stack Overflow
Helps with creating numpy arrays with mixed types. However, if you're looking to combine different multidimensional numpy arrays (with several rows and columns) into one large array of mixed types, don't use numpy.column_stack method because it will convert all of them to one type (convert ints into strings for example). Rather, use pandas concat method instead, which means you turn each multidimensional array into its own dataframe.

PHP: array_reduce - Manual
This function is useful in situations where you need to deal with arrays of associative arrays with numeric keys and you want to merge them into one while preserving the numeric keys.

Like so, for example:

$arr1 = [ [ 1 => 'foo'], [3 => 'bar'], [7 => 'yo'], ..., [101 => 'dogg'] ];
$result = array_reduce($arr1, function ($carry, $item) { return $carry + $item; }, []);

This returns: [ 1 => 'foo', 3 => 'bar' .... 101 => 'dogg'];
