PHP uses method overloading to implement get and set methods that dynamically create attributes.

<?php
class person
{
 private $name;
 private $age;
 private $address;
 private $school;
 private $phonenum;
 public function __call($method,$args)
 {
  $perfix=strtolower(substr($method,0,3));
  $property=strtolower(substr($method,3));
  if(empty($perfix)||empty($property))
  {
   return;
  }
  if($perfix=="get"&&isset($this->$property))
  {
   return $this->$property;
  }
  if($perfix=="set")
  {
   $this->$property=$args[0];
  }
 }
}
$p=new person();
$p->setname(&#39;lvcy&#39;);
$p->setage(23);
$p->setAddress(chengdu);
$p->setschool(&#39;uestc&#39;);
$p->setphonenum(&#39;123456&#39;);
echo $p->getname().&#39;\\n&#39;;
echo $p->getage().&#39;\\n&#39;;
echo $p->getaddress().&#39;\\n&#39;;
echo $p->getschool().&#39;\\n&#39;;
?>
