I’m running nginx v0.8.54 (latest stable), and I’m having issues with  
fastcgi\_split\_path\_info passing the query parameters into PATH\_INFO

e.g., [http://example.com/index.php/foo/bar/?id=1](http://example.com/index.php/foo/bar/?id=1) breaks is passed to  
fcgi as

```auto
SCRIPT_FILENAME = /var/www/index.php (good)
PATH_INFO = /foo/bar/?id=1 (bad)
```

I’ve defined the split in my config as:

```auto
  fastcgi_split_path_info ^(.+\.php)(.*)\??$;

  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  fastcgi_param PATH_INFO $fastcgi_path_info;
```

The second capture group should only grab “/foo/bar/”, am I doing  
something obviously wrong here?

unless of course you’re using the pcre library which can’t handle ??

this actually works: ^(.+.php)([^?]_)._$

scratch that!

regex was a little greedy, should look like: ^(.+.php)(.\*?)?
