Declaring a PHP Class

Thinking back over how long I have been learning PHP, at the very beginning I never could figure out classes, internal properties, and external properties. So now let’s go through a detailed introduction from the start. The code is as follows <?php header(“content-type:text/html;charset=utf-8”); class guests{//declare a class guests private $name; //private property private $gender; function setname($name){ $this->name=$name; } function getname(){ return $this->name; //return the name } function setgender($gender){ $this->gender=$gender; } function getgender(){ return $this->gender; //return the gender } }; $xiaoming=new guests; $xiaoming->setname(“王小明”); $xiaoming->setgender(“男”); $lili=new guests; $lili->setname(“莉莉”); $lili->setgender(“女”); echo $xiaoming->getname().”\t”.$xiaoming->getgender().”
“; echo $lili->getname().”\t”.$lili->getgender(); ?>
