The specific analysis is as follows:

1. $arr [true] is equivalent to $arr [1]; $arr [false] is equivalent to $arr [0].

2. Using null as the key name is equivalent to creating or overwriting a $arr [null], which can be accessed using $arr [null] or $arr ["].

3. When using a number with a decimal point as the key name, the key name will automatically intercept the integer part as the key name.

4. $arr [] = 5, which is added after the array $arr.

Note: the data type of the key name in the array is integer or string.
