header实现302临时重定向

本文实例总结了PHP中Header使用的HTTP协议及常用方法。分享给大家供大家参考。具体方法如下:

 代码如下

复制代码 代码如下:

Header("HTTP/1.1 302 Found");
Header("Location: http://www.111cn.net");

<?PHP
function https($num) {
$http = array (
100 => "HTTP/1.1 100 Continue",
101 => "HTTP/1.1 101 Switching Protocols",
200 => "HTTP/1.1 200 OK",
201 => "HTTP/1.1 201 Created",
202 => "HTTP/1.1 202 Accepted",
203 => "HTTP/1.1 203 Non-Authoritative Information",
204 => "HTTP/1.1 204 No Content",
205 => "HTTP/1.1 205 Reset Content",
206 => "HTTP/1.1 206 Partial Content",
300 => "HTTP/1.1 300 Multiple Choices",
301 => "HTTP/1.1 301 Moved Permanently",
302 => "HTTP/1.1 302 Found",
303 => "HTTP/1.1 303 See Other",
304 => "HTTP/1.1 304 Not Modified",
305 => "HTTP/1.1 305 Use Proxy",
307 => "HTTP/1.1 307 Temporary Redirect",
400 => "HTTP/1.1 400 Bad Request",
401 => "HTTP/1.1 401 Unauthorized",
402 => "HTTP/1.1 402 Payment Required",
403 => "HTTP/1.1 403 Forbidden",
404 => "HTTP/1.1 404 Not Found",
405 => "HTTP/1.1 405 Method Not Allowed",
406 => "HTTP/1.1 406 Not Acceptable",
宝马娱乐在线112222,407 => "HTTP/1.1 407 Proxy Authentication Required",
408 => "HTTP/1.1 408 Request Time-out",
409 => "HTTP/1.1 409 Conflict",
410 => "HTTP/1.1 410 Gone",
411 => "HTTP/1.1 411 Length Required",
412 => "HTTP/1.1 412 Precondition Failed",
413 => "HTTP/1.1 413 Request Entity Too Large",
414 => "HTTP/1.1 414 Request-URI Too Large",
415 => "HTTP/1.1 415 Unsupported Media Type",
416 => "HTTP/1.1 416 Requested range not satisfiable",
417 => "HTTP/1.1 417 Expectation Failed",
500 => "HTTP/1.1 500 Internal Server Error",
501 => "HTTP/1.1 501 Not Implemented",
502 => "HTTP/1.1 502 Bad Gateway",
503 => "HTTP/1.1 503 Service Unavailable",
504 => "HTTP/1.1 504 Gateway Time-out"
);
header($http[$num]);
};

header实现404无法找到页面

//200 正常状态
header('HTTP/1.1 200 OK');

 代码如下

// 301 永久重定向,记得在后面要加重定向地址 Location:$url
header('HTTP/1.1 301 Moved Permanently');

Header("HTTP/1.1 404 Not Found");

// 重定向,其实就是302 暂时重定向
header('Location: http://www.xxxx.com/');

一下函数可实现各种状态的跳转:

// 设置页面304 没有修改
header('HTTP/1.1 304 Not Modified');

 代码如下

// 显示登录框,
header('HTTP/1.1 401 Unauthorized');
header('WWW-Authenticate: Basic realm="登录信息"');
echo '显示的信息!';

/**
* 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 "<meta http-equiv='refresh' content='0;url=$url'>";
}
}
exit;
}

// 403 禁止访问
header('HTTP/1.1 403 Forbidden');

// 404 错误
header('HTTP/1.1 404 Not Found');
