Questions about PHP class loading under namespaces

问一下大家自动装载是自动加载的意思吗，就是会调用spl_autoload_register()之类的函数。

Reply content:

 !--? phpnamespace a;use b\d, c\e as F;new B ()    ; Create an object of class ' B ' defined in namespace ' A '//If not found, try to automatically load class "a\b"   

Ask everyone if automatic loading is automatic loading means that it will call SPL Functions such as _autoload_register ().

Auto Mount here should be auto load The meaning of the . But Spl_autoload_register is not called at the time of New B () -it should have been called before. new B () is automatically loaded simply by invoking the autoloader registered with Spl_autoload_register in the order in which it was previously registered.

For example, there has been a previous registration of two autoloader:

spl_autoload_register (foo ); Spl_autoload_register (bar);  

Then call foo at new B () after calling bar ...
