PHP Auto-load Evolution

1. The first time we call the methods in different pages of the class

Test.phprequire_once ' test1.php '; require_once ' test2.php '; Test1\ceshi (); Call way  namespace \ Function name Test2\ceshi ();//Call way  namespace \ Function name

namespace test1;function Ceshi () {    // file full path and filename  such as  D:\sfc\ceshi\mooc\test1.php}

Namespace Test2;function Ceshi () {echo __file__;//file full path and filename  such as D:\sfc\ceshi\mooc\test2.php}

2. Imagine that each file is manually introduced is too cumbersome, if you can use that to introduce the good, some, there is a function __autoload () {} can be implemented

//the solution is to customize the auto-load function and use Spl_autoload_register to register the auto-load functionSpl_autoload_register (' Autoload2 '); Test\test1:: Ceshi ();//call static method format--namespace name \ class Name:: Static method NameTest\test2::Ceshi ();functionAutoload2 ($class){//Define the Introduction file function//echo $class ===> test\test1    List($namespace,$fileName) =Explode(‘\\‘,$class); require__dir__. ' \\‘.$fileName.‘. Php;}

<? phpnamespace Test; class test1{    publicstaticfunction  Ceshi () {        Echo  __method__; Returns the name of the class and the name of the method

Echo ' </br> ';}}

　　

1 namespace Test; 2 class test2{3      Public Static function Ceshi () {4         Echo __method__ // Returns the name of the class and the name of the method 5         Echo ' </br> '; 6     }7 }
