How to implement page jump using header() in php_PHP tutorial

This article uses the header() function to implement page jumps. We introduce state jumps such as 404, 302, 301, etc. There are many state-defined functions below. Students who need them can test them.

Header implements 302 temporary redirect

代码如下	复制代码
Header("HTTP/1.1 302 Found"); Header("Location: http://www.hzhuti.com");

Header implements 404 page cannot be found

代码如下	复制代码
Header("HTTP/1.1 404 Not Found");

The following functions can jump to various states:

The code is as follows

代码如下

复制代码

/** * 跳转页面 * * 使用header()进行页面跳转,不显示任何内容.如果不能使用header跳转 * @param string $url * @param int $status */ function goto($url,$status=null) { if(!empty($status)) { $status=intval($status); $codes    = array( 100 => "Continue", 101 => "Switching Protocols", 200 => "OK", 201 => "Created", 202 => "Accepted", 203 => "Non-Authoritative Information", 204 => "No Content", 205 => "Reset Content", 206 => "Partial Content", 300 => "Multiple Choices", 301 => "Moved Permanently", 302 => "Found", 303 => "See Other", 304 => "Not Modified", 305 => "Use Proxy", 307 => "Temporary Redirect", 400 => "Bad Request", 401 => "Unauthorized", 402 => "Payment Required", 403 => "Forbidden", 404 => "Not Found", 405 => "Method Not Allowed", 406 => "Not Acceptable", 407 => "Proxy Authentication Required", 408 => "Request Time-out", 409 => "Conflict", 410 => "Gone", 411 => "Length Required", 412 => "Precondition Failed", 413 => "Request Entity Too Large", 414 => "Request-URI Too Large", 415 => "Unsupported Media Type", 416 => "Requested range not satisfiable", 417 => "Expectation Failed", 500 => "Internal Server Error", 501 => "Not Implemented", 502 => "Bad Gateway", 503 => "Service Unavailable", 504 => "Gateway Time-out" ); if (array_key_exists($status,$codes)) { $code    = $status; $msg    = $codes[$status]; $status = "HTTP/1.1 {$code} {$msg}"; } else { $status = null; } } if (!empty($status)) { header($status); } if(!empty($url)) { $url=url($url);header("Location: $url"); if ($code==404) { echo ""; } } exit; }

Copy code

/**
* Jump to page
*
* Use header() to jump to the page without displaying any content. If you cannot use header to jump
* @param string $url
* @param int $status
*/
function goto($url,$status=null)

if(!empty($status))
{
$status=intval($status);
