PHP面向对象的基本写法(区别于java)
?php/*** 这是一个人的对象*/class ClassName {public $name;public $age;public $sex; public static $my = 'static var11';function __construct($name,$age,$sex){ //这里已经是本身的属性了,可以看过$this已经有一个$了,声明了是地址,可以不同再次使
<?php /** * 这是一个人的对象 */ class ClassName { public $name; public $age; public $sex;<br /> public static $my = 'static var11'; function __construct($name,$age,$sex) { //这里已经是本身的属性了,可以看过$this已经有一个$了,声明了是地址,可以不同再次使用地址 $this->name = $name; $this->age = $age; $this->sex = $sex; } function say(){ echo "Hello world";<br> echo self::$my . "\n";<br> } } $student = new ClassName("sun",20,"男"); echo $student->say(); echo "<br>"; echo $student->name; echo "<br>"; echo $student->age; echo "<br>"; echo $student->sex; //调用的时候倒是和java语法差不多,就是“.”变成了“->” ?>
构造方法的名字也进行了统一 __construct();
new 的时候同样是分配一个栈空间的地址指向堆空间的对象区域
调用构造方法parent::__construct() 和java中的super.funName()对比
self::用来访问本类的属性和方法 在类的内部对成员或方法进行访问的<br><br>
