本代码首先通过head进行301转向,如果失败,则通过http-equiv="Refresh"转向,如果不行再通过js进行转向,再不行直接在页面上输出链接地址让用户自己点击链接转向,php确保url转向的方法,感兴趣的小伙伴,下面一起跟随脚本之家 jb51.cc的小编来看看吧。 经测试代码如下:
/**
* 确保url转向
*
* @param
* @arrange (512.笔记) jb51.cc
**/
function safe_redirect($url,$exit=true) {
// Only use the header redirection if headers are not already sent
if (!headers_sent()){
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $url);
// Optional workaround for an IE bug (thanks Olav)
header("Connection: close");
}
// HTML/JS Fallback:
// If the header redirection did not work,try to use various methods other methods
print '<html>';
print '<head><title>Redirecting you...</title>';
print '<meta http-equiv="Refresh" content="0;url='.$url.'" />';
print '</head>';
print '<body onl oad="location.replace(''.$url.'')">';
// If the javascript and meta redirect did not work,// the user can still click this link
print 'You should be redirected to this URL:<br />';
print "<a href="$url">$url</a><br /><br />";
print 'If you are not,please click on the link above.<br />';
print '</body>';
print '</html>';
// Stop the script here (optional)
if ($exit) exit;
}
