HomeBackend DevelopmentPHP Tutorial PHP实现页面跳转的三种技巧

PHP页面跳转实现的功能就是将网站中一个网页跳转到另一个网页中。对于刚刚学习PHP语言的朋友来说,是必须要掌握的基础方法。

PHP被许多程序员用来开发WEB的首选语言。在实际开发中,网站的各项功能都可以通过PHP语言的编写来满足,比如PHP页面跳转这一方法。

Web系统中,从一个网页跳转到另一个网页,是LAMP项目中最常用的技术之一。页面跳转可能是由于用户单击链接、按钮等引发的,也可能是系统自动产生的。 此处介绍PHP中常用的实现页面自动跳转的方法。

PHP页面跳转一:header()函数

header()函数是PHP中进行页面跳转的一种十分简单的方法。header()函数的主要功能是将HTTP协议标头(header)输出到浏览器。

header()函数的定义如下:

void header (string string [,bool replace [,int http_response_code]])

可选参数replace指明是替换前一条类似标头还是添加一条相同类型的标头,默认为替换。

第二个可选参数http_response_code强制将HTTP相应代码设为指定值。 header函数中Location类型的标头是一种特殊的header调用,常用来实现页面跳转。注意:1.location和“:”号间不能有空格,否则不会跳转。

2.在用header前不能有任何的输出。

3.header后的PHP代码还会被执行。例如,将浏览器重定向到php中文网下载站

< ?php 
//重定向浏览器 
header("Location: http://www.php.cn/xiazai"); 
//确保重定向后,后续代码不会被执行 
exit;
?>

PHP页面跳转二:Meta标签

Meta标签是HTML中负责提供文档元信息的标签,在PHP程序中使用该标签,也可以实现页面跳转。 若定义http-equiv为refresh,则打开该页面时将根据content规定的值在一定时间内跳转到相应页面。

若设置content="秒数;url=网址",则定义了经过多长时间后页面跳转到指定的网址。例如,使用meta标签实现疫苗后页面自动跳转到php中文网下载站

< meta http-equiv="refresh" 
content="1;url=http://www.php.cn/xiazai">

例如,以下程序meta.php实现在该页面中停留一秒后页面自动跳转到http://www.php.cn/xiazai

< ?php   
$url = "http://www.php.cn/xiazai"; ?> 
< html>   
< head>   
< meta http-equiv="refresh" content="1;  
url=< ?php echo $url; ?>">   
< /head>   
< body>   
页面只停留一秒……   
< /body> 
< /html>

PHP页面跳转三:JavaScript

例如,此代码可以放在程序中的任何合法位置。

< ?php  
$url = "http://bbs.lampbrother.net";  
echo "< script language=&#39;javascript&#39; 
type=&#39;text/javascript&#39;>";  
echo "window.location.href=&#39;$url&#39;";  
echo "< /script>";  
?>

实用例子:

//输出提示,并后退到前一页
echo "<script>alert(&#39;你没有权限!&#39;);location.href=&#39;".$_SERVER["HTTP_REFERER"]."&#39;;</script>";

以上就是我们向大家介绍的三种PHP页面跳转实现方法。

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
