代码片段 PHP页面重定向

考虑比较完善的页面重定向方法。

function get_status_header_desc($code) {
    $header_to_desc = 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',

            411 => 'Length Required',
            412 => 'Precondition Failed',
            413 => 'Request Entity Too Large',
            414 => 'Request-URI Too Long',
            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 Timeout',
            505 => 'HTTP Version Not Supported'
            );

    if ( isset( $header_to_desc[$code] ) ){
        return $header_to_desc[$code];
    }
    return '';
}

function redirect($pUrl='/',$delay=0,$permanent=false)  {
    //如果之前的环境已经发送过head了 就吐出来meta标签
    if (headers_sent($file,$line)) {
        echo "<meta http-equiv=\"refresh\" content=\"{$delay};URL={$pUrl}\" />";
        exit;
    }
    if ($delay > 0) {
        header("Refresh:{$delay}; url={$pUrl}");        exit;
    }

    $status = $permanent ? 301 : 302;
    $statusHeader = sprintf("HTTP/1.1 %s %s",$status,SOSO_Util_Util::get_status_header_desc($status));
    header($statusHeader); 
    header("Location:{$pUrl}");
}

使用方式

redirect('/home', 0 ,false);
