There is nothing special about the SPL name. it's just because the full name is Standard PHP Library.

It is an extension introduced by PHP 5.0. of course, it is enabled by default. it cannot cancel compilation at the beginning of 5.3. it defines a series of standard data structures and interfaces, it also provides several methods to facilitate the use of PHP's autoload system.
