找到 404 的错误页面

Question

We are redirecting 404 error pages to a php page to track. We had used .htaccess code:

ErrorDocument 404 404.php?sr=%{REQUEST_URI}

but when on our 404.php page we are trying to fetch:

$requri = getenv ("REQUEST_URI");

It is not showing us the pagename from which user got redirected like abc.html and we want to detect that page name, can anyone help in this matter?

Answer 1

You can use mod-rewrite to redirect a non-existent request to 404.php :

RewriteEngine on


RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ /404.php?sr=$1 [NC,L] 

-d matches an existing directory and -f matches an existing file on the server. RewriteCond checks to see that the requested filename is not ! an existing directory or file before it redirects the request to /404.php. You can also replace $1 with %{REQUEST_URI} to get the full uri.
