PHP7 Anonymous class php7.0 PHP7 compile and install Apache php7.0 configuration

Anonymous classes Create a one-time simple object, just like anonymous functions

 
       /** * Created by Phpstorm. * User:bee * date:2016/4/24 * time:00:17 *
  *Echo' anonymous function ';$anonymous _func= function(){return' function ';};Echo$anonymous _func();Echo'
';Echo''; classcommon { Public$default=Ten; function__construct($key){$this->getval ($key); } Public functiongetval(int $i):int{$this-default+=$i;return$this-default+0.1; }}Echo' famous function ';Echo'

';Echo(New class(2) extendscommon{})->getval ( -);

After the anonymous class is nested into the normal class, the external class (Outer Class) cannot be accessed
Private, protected (protected) method, or property. In order to access the external class (Outer Class) protected
Properties or methods, anonymous classes can be extend (extended) In addition to the class. In order to use the private of the external class (Outer Class)
property, which must be passed in through the constructor:

 !--? php 
    
     class  
     Outer  {
     private     $prop = 
     1 ;    
     protected  $prop 2 = 
     2 ;    
     protected  function func1 () {
     return  
     3 ; 
     public  function Func2 () {
     return  
     new  
      class  ($  t His ->  prop )   extends    Outer  { 
     private             $prop 3;            
     public  function __construct ($prop) {$ 
     this ->prop3 = $prop; 
     public  function func3 () {
     return  $ 
     this -&            GT;PROP2 + $ 
     This ->PROP3 + $ 
     this ->func1 ();    }        }; }}echo (
     new  Outer)->func2 ()->func3 (); 
    //6  
    

Anonymous functions can implement closures, then the corresponding anonymous class can also implement closures

   /** * Created by Phpstorm. * User:bee * date:2016/4/24 * time:1:51 * *$arr=Array(); for($i=0;$i<3;$i++){$arr[] =New class{ Public$index=0; function__construct() {Echo' Create
'; } Public functiongetval($index){$this->index =$index;Echo$this->index; } Public functiongetindex(){Echo$this->index; }    };}$arr[2]->getval (2);Echo'
'; Var_dump ($arr[1]);$arr[1]->getindex ();

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the PHP7 anonymous class, including the PHP7 aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
