简单说一下就是
-> 调用对象的成员
=> 指定下标
下面来看几个实例关于-> 与=>代码,让你更清楚是什么用法与功能并且有什么区别了。
*/
// =>用法,可用到数组array,赋值与foreach赋值
$array = array("addr" => "www.111cn.net","tel" => "11111111");
print_r($array);
/*
结果为
Array
(
[addr] => www.111cn.net
[tel] => 11111111
)
*/
//用来foreach实例
foreach( $array as $v =>$_v )
{
echo $_v,'
';
}
/*
结果
www.111cn.net
11111111
*/
// ->用法上面说了是用于对象的,那我们就来做个实验
class user{
var $url ='www.111cn.net';
public function showUrl()
{
echo $this->url;
}
}
//调用 user类方法
$u = new user();
$u->showUrl();
/*
输出结果为 www.111cn.net
