run code in 300+ PHP versions simultaneously
<?php // 费了我好大功夫, 把这些都总结到一个例子里面了 // PHP5.0 - PHP5.5 测试通过 class A { //类常量 const constValue = "constValue\n"; //类属性 public $property = "properties\n"; //静态属性 static public $staticProperty = "staticProperty\n"; //普通函数 public function func() { } //静态函数 static public function staticFunc() { } } $xxoo = new A; //访问实例的属性 print $xxoo->property; //访问实例的函数 print $xxoo->func(); //也可以借助实例来访问静态成员 print $xxoo->staticFunc(); print $xxoo->staticProperty; //如果不借助实例,那就直接用类名加双冒号 print A::staticFunc(); print A::constValue; //静态属性要加美元符号 print A::$staticProperty; //继承类A class B extends A { //覆盖父类的属性 public $property = "covered-properties\n"; //覆盖父类的静态属性 static public $staitcProperty = "covered-staitcProperties\n"; //覆盖父类的函数 public function func() { //访问自己的属性 print $this->property; //访问从父类继承来的静态属性 print self::$staticProperty; //强制指定访问父类(而不是自己)的属性 print parent::$property; //强制指定访问父类(而不是自己)的函数 print parent::func(); } //覆盖父类的静态函数 static public function staticFunc() { //因为没有$this, 所以用self访问自己的静态属性 print self::$staitcProperty; //强制访问父类的静态属性 print parent::$staitcProperty; } } //运行一下上面的例子 $xxoo = new B; $xxoo->func(); B::staticFunc();

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
