类的自动加载

<?php
spl_autoload_register(function($class){
    require $class.'.php';
});

类的基本形式

class Player{
    public $name = 'Jordan'; 
    public $height;
    public $team;
    protected $playerNum;
    public function __construct($name,$height,$team,$weight){
        $this->name = $name;
        $this->height = $height;
        $this->team = $team;
        $this->weight = $weight;
    }
    public function jog(){
        return  "$this->name is jogging, weighing $this->weight<br>";
    }
    public function shoot(){
        return  "$this->name is shooting, his height is $this->height<br>";
    }
}

类的调用

$np2 = new Player('kobe','206cm','Laker',"85kg");
echo $np2->name;
echo $np2->shoot();

类的静态成员

class User
{
    public static $name = '胡歌';
    protected $_config = [
        'auth_on'=>'true',
        'auth_type'=>1,
    ];
    public static $nation = "China";
    private static $salary ;
    static $count = 0;
    public function __construct($name,$salary){
        self::$name = $name;
        self::$salary = $salary;
        self::$count++;
    }
    public  function getConfig(){
        return sprintf('认证开关:%s<br>,认证类型:%d',$this->_config['auth_on'],$this->_config['auth_type']);
    }
    public static function getCount()
    {
        return sprintf('User类被实例化了%d次<br>',self::$count);
    }
