I'm looking at the PHP Manual, and I'm not seeing a section on data structures that most languages have, such as lists and sets. Am I just blind or does PHP not have anything like this built in?

The only native data structure in PHP is array. Fortunately, arrays are quite flexible and can be used as hash tables as well.

However, there is SPL which is sort of a clone of C++ STL.
