实例化php类的时候如何传参???当我们实例化一个php类的时候，要怎么传递参数呢？这取决于该类的构造方法。

例：

person.class.php

<?php

class person{

var $name;

var $color;

var $sex;

var $age;

function __construct($name,$age='',$sex='boy'){

$this->name = $name;

$this->age = $age;

$this->sex = $sex;

$this->color = 'yello';

}

function eat(){

echo $this->name.'要吃饭';

}

function xinxi(){

echo $this->name.' is '.$this->sex.' and age is '.$this->age.' fuse is '.$this->color;

}

}

?>

son.php

<?php

include('person.class.php');

$son = new person('cuihua',25,'girl');//此处的参数传递要和类的构造方法里面的参数顺序对应

//$son->xinxi();//cuihua is girl and age is 25 fuse is yello
$son->name = '田妞';

$son->eat();//田妞要吃饭

?>
