/** @mainpage SPL - Standard PHP Library
*
* SPL - Standard PHP Library
*
* SPL is a collection of interfaces and classes that are meant to solve
* standard problems and implements some efficient data access interfaces
* and classes. You'll find the classes documented using php code in the
* file spl.php or in corresponding .inc files in subdirectories examples
* and internal. Based on the internal implementations or the files in the
* examples subdirectory there are also some .php files to experiment with.
*
* The .inc files are not included automatically because they are sooner or
* later integrated into the extension. That means that you either need to
* put the code of examples/autoload.inc into your autoprepend file or that
* you have to point your ini setting auto_prepend_file to that file.
*
* Below is a list of interfaces/classes already availabel natively through
* the SPL extension grouped by category.
*
* 1) Iterators
*
* SPL offers some advanced iterator algorithms:
*
* - interface RecursiveIterator extends Iterator
* - interface OuterIterator extends Iterator
* - class RecursiveIteratorIterator implements OuterIterator
* - abstract class FilterIterator implements OuterIterator
* - class ParentIterator extends FilterIterator implements RecursiveIterator
* - interface SeekableIterator extends Iterator
* - class LimitIterator implements OuterIterator
* - class CachingIterator implements OuterIterator
* - class RecursiveCachingIterator extends CachingIterator implements RecursiveIterator
* - class IteratorIterator implements OuterIterator
* - class NoRewindIterator implements OuterIterator
* - class EmptyIterator implements Iterator
* - class InfiniteIterator extends IteratorIterator
* - class AppendIterator implements OuterIterator
* - class RegexIterator extends FilterIterator
* - class RecursiveRegexIterator extends RegexIterator implements RecursiveIterator
*
* 2) Directories and Files
*
* SPL offers two advanced directory and file handling classes:
*
* - class SplFileInfo
* - class DirectoryIterator extends SplFileInfo implements Iterator
* - class RecursiveDirectoryIterator extends DirectoryIterator implements RecursiveIterator
* - class SplFileObject extends SplFileInfo implements RecursiveIterator, SeekableIterator
*
* 3) XML
*
* SPL offers an advanced XML handling class:
*
* - class SimpleXMLIterator extends simplexml_element implements RecursiveIterator
*
* 4) Array Overloading
*
* SPL offers advanced Array overloading:
*
* - class ArrayObject implements IteratorAggregate, ArrayAccess, Countable
* - class ArrayIterator implements Iterator, ArrayAccess, Countable, SeekableIterator
* - class RecursiveArrayIterator extends ArrayIterator implements RecursiveIterator
*
* As the above suggest an ArrayObject creates an ArrayIterator when it comes to
* iteration (e.g. ArrayObject instance used inside foreach).
*
* 5) Counting
*
* - interface Countable allows to hook into the standard array function count().
*
* 6) Exception%s
*
* SPL provides a set of standard Exception classes each meant to indicate a
* certain problem type.
*
* - class LogicException extends Exception
* - class BadFunctionCallException extends LogicException
* - class BadMethodCallException extends BadFunctionCallException
* - class DomainException extends LogicException
* - class InvalidArgumentException extends LogicException
* - class LengthException extends LogicException
* - class OutOfRangeException extends LogicException
* - class RuntimeException extends Exception
* - class OutOfBoundsException extends RuntimeException
* - class OverflowException extends RuntimeException
* - class RangeException extends RuntimeException
* - class UnderflowException extends RuntimeException
*
* 7) Observer
*
* SPL suggests a standard way of implementing the observer pattern.
*
* - interface SplObserver
* - interface SplSubject
* - class SplObjectStorage
*
* 8) @ref Examples
*
* The classes and interfaces in this group are contained as PHP code in the
* examples subdirectory of ext/SPL. Sooner or later they will be moved to
* c-code.
