                PHP與JavaScript創建對象的方法類似,都可以用new關鍵字來創建,而且都有構造函數,只是語法有些不一樣,具體如下: class Person{ public $name; public $height; function __construct($a,$b){ $this->name = $a; $this->height = $b; } function show(){ echo '姓名:'.$this->name; echo '<br/>'; echo '身高:'.$this->height; } } $person = new Person('fxxy','165cm'); $person->show(); 上面的代碼首先定義一個Person的類,然后定義類的屬性$name和$height,還有構造函數__construct(注意是兩個下劃線),通過__construct來初始化對象屬性,另外還有一個show方法。 通過new關鍵字實例化創建一個對象,這個對象就可以執行它的show方法。 與JavaScript所不同的是,PHP需要通過一個單獨的構造函數來承載它的屬性,但是js可以直接定義屬性,如下: function Person(name,height){ this.name = name; this.height = height; } Person.prototype.show = function(){ console.log(this.name); console.log(this.height); } var person = new Person('fxxy','165cm'); person.show();
