About this binding
class Human {
public $name = 'lisi'; public function who() {
echo $this->name;
} /*
public function test() {
echo $name;
}
*//*
和java、c++相比
方法体内想访问调用者的属性，必须用$this
如果不加，则理解为方法内部的一个局部变量.
*/}$a = new Human();echo $a->name,'<br >'; //lisi$a->who(); //lisi//$a->test();
The above is the detailed content of PHP this binding. For more information, please follow other related articles on the PHP Chinese website!
