Pre-5.3 SPL Features
● Classes: ArrayObject, SplFileInfo...
● Interfaces: ArrayAccess, Countable...
● Exceptions: BadFunctionCallException...
● Functions: spl_autoload_register...
So What's New?
In comparison to the STL:
● Iterators? Nope.
● Algorithms? Nope.
● Functors? Nope.
● Well, there's only one thing left then...
“A container is a class, a data structure,
or an abstract data type whose instances
are collections of other objects. They are
used to store objects in an organized way
following specific access rules.”
“Container (data structure)” - Wikipedia
