What is the best way to get the URL of a 404'd file after redirect?
I'm working with a PHP site that needs to log errors to a database. As such, I've set up a .htaccess file as follows:
ErrorDocument 404 /404.php
404.php contains all of the logging functions necessary to insert the log into the database. What I'm having problems with is retrieving the URL of the file that triggered the 404.
Here are the contents of the $_SERVER superglobal array:
[HTTP_HOST] => {omitted}
[HTTP_USER_AGENT] => Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.7) Gecko/20091221 Firefox/3.5.7
[HTTP_ACCEPT] => text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
[HTTP_ACCEPT_LANGUAGE] => en-us,en;q=0.5
[HTTP_ACCEPT_ENCODING] => gzip,deflate
[HTTP_ACCEPT_CHARSET] => ISO-8859-1,utf-8;q=0.7,*;q=0.7
[HTTP_KEEP_ALIVE] => 300
[HTTP_CONNECTION] => keep-alive
[PATH] => /usr/local/bin:/usr/bin:/bin
[SERVER_SIGNATURE] =>
[SERVER_SOFTWARE] => Apache/2.2.8 (Ubuntu)
[SERVER_NAME] => {omitted}
[SERVER_ADDR] => {omitted}
[SERVER_PORT] => 80
[REMOTE_ADDR] => {omitted}
[DOCUMENT_ROOT] => {omitted}
[SERVER_ADMIN] => [no address given]
[SCRIPT_FILENAME] => /404.php
[REMOTE_PORT] => 19274
[GATEWAY_INTERFACE] => CGI/1.1
[SERVER_PROTOCOL] => HTTP/1.1
[REQUEST_METHOD] => GET
[QUERY_STRING] =>
[REQUEST_URI] => /404.php
[SCRIPT_NAME] => /404.php
[PHP_SELF] => /404.php
[REQUEST_TIME] => {omitted}
Any suggestions? Everything that I've read recommends the HTTP_REFERER item, but it doesn't seem to exist.
Thanks in advance.
REQUEST_URI旨在包含请求的URL路径和查询。
