Undoubtedly, SPL tries to solve common data structure implementation issues for PHP programmers. Many of us are either afraid or reluctant to implement proper data structure while programming. SPL comes with implementation of all basic data structure and, hence, makes life easier for developers by using built-in classes and methods. Since SPL comes as a bundle with PHP, we do not need to install it separately or enable any extension for it. In this section, we will discuss some of the common SPL classes in brief:
