PHP 页面跳转到另一个页面的多种方法方法总结
如何在PHP中从一个页面重定向到另外一个页面呢？这里列出了三种办法，供参考。
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：
代码如下:
<?
if (isset($url))
{
Header("HTTP/1.1 303 See Other");
Header("Location: $url");
exit; //from www.w3sky.com
}
?>注意一下，"Localtion:"后面有一个空格。
二、用HTML标记
用HTML标记，就是用META的REFRESH标记，举例如下：
代码如下:
<? if (!isset($url)) exit;?> <HTML> <HEAD> <META HTTP-EQUIV="REFRESH" CONTENT="5; URL=<? echo $url;?>> </HEAD> <BODY> </BODY> </HTML>
三、用脚本来实现
例如下：
代码如下:
<? $url="//www.jb51.net"; echo "<!--<scrīpt LANGUAGE="Javascrīpt">"; echo "location.href='$url'"; echo "</scrīpt>-->"; ?>
下面是补充
第四种:
echo "< meta http-equiv=\\"Refresh\\" content=\\"秒数; url=跳转的文件或地址\\" > ";
其中:XX是秒数,0为立即跳转.refresh 是刷新的意思.Url 是要跳转到的页面.
第五种:利用script实现
<script>url="submit.php";window.location.href=url;</script>
第六种:利用script实现,所不同的是使用 open 语句.且可以限制原窗口还是父窗口,子窗口或者新窗口.
<script>url="submit.php";window.open(\'url,\'\',\'_self\');</script>
其中 更改\'_self\' 就可以实现跳转限制原窗口还是父窗口,子窗口或者新窗口.第七种:利用php自带函数发送头部信息
header("Location: Url");
速度最快,功能强大...但是有个问题必须指出:如果在使用这个函数前已经有html输出,哪怕是一个空格.那么在页顶会显示错误信息

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
