你new错了，要new Player类
<?php
class Human{
public $name;
public $height;
public $weight;
public function eat($food){
echo $this->name."'s eating ".$food."\n";
}
}
class Player extends Human{
function __construct($name,$height,$weight){
$this->name=$name;
$this->height=$height;
$this->weight=$weight;
}
}
$jor = new Player("jor","198cm","75kg");
echo $jor->name."\n";
$jor->eat("orange");
?>
<p><?php
class Human
{
public $name;
public $height;
public $weight;
public function eat($food){
echo $this ->name."'s eating ".$food."\n";
}
}
class Player extends Human
{
function __construct($name,$height,$weight)
$this->name=$name;
$this->height=$height;
$this->weight=$weight;
}
$jor=new Human("jor","198cm","75kg");
echo $jor ->name."\n";
$jor ->eat("orange");
?>
