PHP SPL standard library data structure stack (Splstack) Introduction This article mainly introduces the PHP SPL standard library data structure stack (splstack) Introduction, stack (stack) is a special linear table, because it can only at one end of the linear table to insert or delete elements (i.e., into the stack and out of the stack), the need for friends can refer to the next A stack is a special lin

The PHP SPL standard library provides functions for processing such as automatic loading, iterator processing, and so on. Spl_autoload_extensions () Add spl_autoload () the file name extension that can be loadedSpl_autoload_register () registers the function into the SPL __autoload function stack.

The SPL data operation layer and model layer are complete. According to the UML: Java Program The author's DX practices in the member guide pick out the most important ideas. Let's run the program first. In the past few days, I have been playing the frozen throne, and I am not very familiar with SPL, therefore, the progress is slow, but most of the functions are completed. In addition to the two above, the

Php arrays and spl fixed arrays php fixed arrays belong to a data structure of the php Standard Library (spl. Compared with a php ordinary array, a fixed array can only define its subscript using an integer, and as shown in the name, it is a fixed length, which has the advantage of less memory than a common array, and is faster, the specific cause is analyzed below. first, a simple test will be conducted to

The last time you used pure PHP to implement an observer pattern (PHP watcher mode), now using PHP standard library SPL to implement the Observer mode at a time, the advantage is: randomly generate the observer you want to use!Using PHP Standard library SPL in implementing Observer mode

The php Standard Library spl is used to implement the observer mode. The last time the pure php is used to implement the observer mode (php observer mode), the following advantages apply to the php Standard Library spl: generate the observer you want to use at will!

bottom layer is implemented by the stack is an advanced data structure, so some of the Splstack class inherited from the Spldoublylinkedlist class methods have some understanding of the different, such as the Rewind method, SPL uses the Rewind method after the pointer points to the top of the stack, the push and pop operations are the top elements of the stack, and the unshift and shift operations are the stack-bottom elements !--?

The main data structures used by PHP SPL (standard PHP Library) are: Doubly linked list (Spldoublylinkedlis), Stack (splstack), queue (Splqueue), Heap (Splheap), Dagen ( SPLMAXHEAP), small Gan (splminheap), Priority queue (Splpriorityqueue), fixed array (splfixedarray), Object Store (splstorageobject).
