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,将浏览器重定向到冠威博客
//重定向浏览器
header("Location: http://www.guanwei.org");
//确保重定向后,后续代码不会被执行
exit;
?>
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www.guanwei.org。
$url = "http://www.guanwei.org"; ?>
">
页面只停留一秒……
PHP页面跳转三、JavaScript(常用、推荐)
例如,此代码可以放在程序中的任何合法位置。
以上就是我们向大家介绍的三种PHP页面跳转实现方法$url = "http://www.guanwei.org";
echo "";
?>

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,
