Learning The Standard PHP Library

What is the Standard PHP Library- Introducing SPL iterators Using SPL iterators

Combining iterators with AppendIterator Converting between arrays and iterators Creating a custom filter with CallbackFilterIterator Creating a custom filter with RecursiveFilterIterator Creating a recursive callback filter Creating a repeat sequence with InfiniteIterator Extending FilterIterator to create a reusable filter Extending RecursiveIteratorIterator to build nested lists

SplMinHeap and SplMaxHeap Finding important information with SplPriorityQueue Merging values from different iterators with MultipleIterator Understanding heaps

Generating an ASCII graphic tree with RecursiveTreeIterator Exporting data to a download file with SplTempFileObject Using SplFileObject to convert a CSV to an array Extracting data from XML with RegexIterator and SimpleXML

Specifying a range of items with LimitIterator Speeding up array access with SplFixedArray Using multidimensional arrays with iterators Using RecursiveCachingIterator with multidimensional structures Using regular expressions to filter directories with RegexIterator Filtering a directory with GlobIterator Filtering values from JSON Getting information about files with SplFileInfo Inspecting directories recursively with RecursiveDirectoryIterator Inspecting single directories with DirectoryIterator Inspecting single directories with FilesystemIterator NoRewindIterator and EmptyIterator Overriding the RecursiveFilterIterator constructor Sorting XML and JSON with SplDoublyLinkedList Sorting XML and JSON with SplHeap
