Which is the faster variable $ [] or array_push (variable $, $ newValue)?

What happens faster when adding variables to an array?

• array_push (variable $, $ new_value);

and please indicate the difference between them, if any.

The holder of Empy does not check, the variable is an array at first as array_push does. If array_push finds that the variable is not an array, it displays a warning message if E_ALL error reporting is enabled.

So, array_push is safer than [], while this is further modified by PHP developers.

$variable[] seems a lot faster:
