Redirect if something follows a directory, but not the directory itself – Apache

I’d like to redirect what follows a URI, but I keep running into trouble.

Basically, I’d like /from/here/1234 redirected to /to/there.php?id=1234. But I can only get it to work if the URI is formatted with something after my pattern, such as /form/here/1234/edit.

This is the “working” rule:

RewriteEngine on

RewriteCond "%{REQUEST_URI}" !-d
RewriteRule ^from/here/(.*)/edit/?$ /to/there.php?id=$1

I have tried it with and without the RewriteCond, with the following alterations:

• If I remove /edit, so that the rule is

  RewriteRule ^from/here/(.*)/?$ /to/there.php?id=$1`
  

  I get an “Internal Server Error”, and “Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.”

  I cannot access /from/here or /from/here/ with this rule.

• If I add a leading slash, remove /edit and ?, so that the rule is

  RewriteRule ^/from/here/(.*)/$ /to/there.php?id=$1
  

  I can access /from/here and /from/here/ with this rule, but not /from/here/1234 (404).

  I created a test 404 page just to print the $_SERVER variable, and nothing looks strange with the REQUEST_URI (i.e. showing as /from/here/1234).

• If I remove /edit and ?, so that the rule is

  RewriteRule ^from/here/(.*)/$ /to/there.php?id=$1
  

  It works only if there is a trailing slash, unless I add the rule

  RewriteRule ^from/here/([a-z0-9-]+)$ /from/here/$1/ [NC]
  

  While this works, it just doesn’t feel right…

I have to be missing something simple/fundamental here, because I have struggled to find anything helpful on my own (which almost always means I’ve boneheadedly missed something “palm-face”/”head-wall”-worthy). I’m not exceedingly familiar with editing the .htaccess file, so that hasn’t helped matters.

TL;DR – I would like to redirect what follows a slash, but only if there is in fact something that follows it. Forward /from/here/1234, but not /from/here or /from/here/.
