Standard PHP Library (SPL) and data structures

the same old php Library (SPL), is one of the exceptional viable features of the personal home page language in last few years. SPL became created to resolve common issues which had been missing in php. SPL prolonged the language in many methods however one of the striking capabilities of SPL is its aid of facts structures. though SPL is used for plenty different purposes, we’re going to attention on the records structure part of SPL. SPL comes with center Hypertext Preprocessor installations and does now not require any extension or exchange in configurations to allow it.
SPL presents a set of fashionable information systems via object-orientated Programming in Hypertext Preprocessor. The supported facts structures are:
Doubly connected lists: it’s far enforce

  • Doubly linked lists: It is implemented in SplDoublyLinkedList.
  • Stack: It is implemented in SplStack by using SplDoublyLinkedList.
  • Queue: It is implemented in SplQueue by using SplDoublyLinkedList.
  • Heaps: It is implemented in SplHeap. It also supports max heap in SplMaxHeap and min heap in SplMinHeap.
  • Priority queue: It is implemented in SplPriorityQueue by using SplHeap.
  • Arrays: It is implemented in SplFixedArray for a fixed size array.
  • Map: It is implemented in SplObjectStorage.

In coming chapters, we are going to explore each of the SPL statistics shape implementations and understand their execs and cons, in conjunction with their overall performance analysis with our implementation of corresponding records systems. however as those information structures are already built in, we will use them for a quick turnaround of features and programs.

After the discharge of personal home page 7, every person become glad with the overall performance increase of the Hypertext Preprocessor application in standard. Hypertext Preprocessor SPL is not having the similar overall performance boost in lots of instances, but we’re going to investigate the ones in upcoming chapters.
