Just curious. When pushing an array on another:
array_push($array_1, $array_2);
I get the usual behavior, but when I push a pdo query->fetchAll which contains and returns an array, nothing happens.
array_push($array_1, $query->fetchAll());
What is interesting to me is, if I assign the query object to a variable:
$array_fetchAll = $query->fetchAll();
array_push($array_1, $array_fetchAll);
It works like expected.
The only way this would work is using PHP version 5.5.X or above where a new feature allow functions to be dereferenced directly to access individual elements.
For example echo $stmt->fetchAll()[0]; would not work if you running PHP older than 5.5.x
array_push requires an array as parameter, if you are using older PHP you must store $query->fetchAll() into a variable.
