php中定义类
<?phpclass Person{ //定义了一个Person类
public $name; //定义属性name
public $age; //定义属性age
function__construct($name,$age){
$this->name =$name;
$this->age = $age;
}
function say( ) //定义方法say( )
{ echo "my name is ".$this->name."<br>";}
}
$zhangsan=new Person(); //生成对象zhangsan
$zhangsan->name="zhangsan"; //给对象中的name赋值
$zhangsan->age=26; //给对象中的age赋值
$zhangsan->say(); //调用方法say()
echo "age is ".$zhangsan->age; //输出age值
?>
注：英文句号（.）可将字符串连接合并成新的字符串。
