SPL is a collection of PHP interfaces and classes that are meant to solve standard problems. This tag is not to be confused with the [shakespeare-lang] tag for Shakespeare Programming Language

SPL stands for Standard PHP Library. It is a collection of PHP interfaces and classes that are meant to solve standard problems. It contains a large set of predefined iterators, data-structures, interfaces and exceptions that can be used and extended.

Documentation can be found here. It is available by default from PHP 5.0.0 onwards.

How to sort an SplFixedArray?
