How to add an element to another mass (multi-dimensional)

[shizuka]

There is:

$families = array(array("Tom", "Alice"), array("Bob", "Kate"));

We need to add a set of elements to:

$families = array(array("Tom", "Alice"), array("Bob", "Kate"), array("Alex", "Bob"));

We can use the function. https://www.php.net/manual/ru/function.array-push.php which adds one or more elements to the end of the mass.

The same effect can be achieved:

$arr[] = YOUR_CUSTOM_ARRAY

I mean, to write the name of the mass where new data will be added, beyond square brackets and further attribution
