页面跳转可能是由于用户单击链接、按钮等触发的,也可能是系统自动产生的。页面自动跳转在WEB开发中经常用到,而且根据需求可以采用不同的跳转方式,比如提示操作信息后延时跳转等, 本文总结了WEB开发中常见的几种页面跳转方法。
PHP header()函数跳转
PHP的header()函数非常强大,其中在页面url跳转方面也调用简单,使用header()直接跳转到指定url页面,这时页面跳转是302重定向:
$url = "http://www.bitsCN.com/"; header( "Location: $url" );
我们有可能会遇到特殊的跳转时,比如网站改版有个页面地址要做301重定向,当然你可以通过web配置rewrite来实现,但现在我要告诉大家,可以使用php的header()函数做301跳转,代码如下:
//301跳转 header( "HTTP/1.1 301 Moved Permanently" ); header( "Location: $url" );
Meta设置跳转
html中的meta信息里可以直接设置跳转,可以设置跳转延迟时间和跳转url,经常应用,比如支付完了告诉用户支付成功并跳转到订单页面,代码非常简单,就在
中加上一句:
<meta http-equiv="refresh" content="5;url=http://www.bitsCN.com">
以上代码表示在5秒钟后页面会自动跳转到http://www.bitsCN.com。
Javascript跳转
Javascript跳转也非常简单,直接一句话:
<script> window.location.href="http://www.bitsCN.com"; </script>
注意,上面这段代码直接跳转后,在目标页面地址中是获取不到来路(referer,也叫来源)的,在实际项目中,遇到有客户要求跳转要带来路(即目标网页可以获取到页面从哪里跳转来的),这时,我们可以用javascript模拟一次点击,然后跳转就满足了客户的需求。
<script> //有来路 var aa = document.createElement("a"); aa.setAttribute("href","http://www.bitsCN.com"); var bodys=document.getElementsByTagName("body")[0]; bodys.appendChild(aa); aa.click(); </script>
当然,实际开发中我们可以把后面两种方式整合到PHP中去,便于适用各种跳转需求。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
