------Solution--------------------
The manual has:
New/modified with square brackets syntax
You can change an existing array by explicitly setting the value.

This is done by assigning a value to the array by specifying the key name within the square brackets. You can also omit the key name, in which case a pair of empty brackets ("[]") are added to the variable name. $arr [key] = value;
$arr [] = value;
Key can be an integer or string
Value can be any value.



------Solution--------------------
$g [] is assigned to the array $g, and in your case the index starts at 0.
------Solution--------------------
$g [] is an empty array.
