学习PHP重定向的三种方法

    一、用HTTP头信息

    也就是用PHP的HEADER函数。PHP里的HEADER函数的作用就是向浏览器发出由HTTP协议规定的本来应该通过WEB服务器的控制指令,例如:声明返回信息的类型("Context-type: xxx/xxx"),页面的属性("No cache", "Expire")等等。

    用HTTP头信息重定向到另外一个页面的方法如下:

 

$url = http://www.bkjia.com;
if (isset($url))
{
Header("Location: $url");
}
?>


    注意一下:"Localtion:"后面有一个空格,不加有时也可以,但为了正确性还是加上为好。

    二、用HTML标记

    用HTML标记,就是用META的REFRESH标记,举例如下:

 

$url = http://www.bkjia.com;
if (!isset($url))     
{
exit('没有要跳转的地址呦');
}
?>








    注意一下:其中content="5; url='http://www.bkjia.com' ",表示跳转的地址以及5秒后执行。

    三、用脚本来实现

 

php
$url=http://www.bkjia.com;
echo "";
?> 

 


    使用header的方法最好,这样页面的跳转速度更快点,用户从视觉上不易察觉整页的跳转,而只是局部的变化!
