== Description ==

This PHP function will reduce long strings to shorter strings, by trimming out the middle. It can be used on any string, but was inspired by the need to reduce URLs that are

<code>http://super.really.long.urls/so/long/they/cannot/really_fit_in_one/field,then</code>

I'd like to reduce the middle of the URL to "[...]"

<code>http://super.really.long.urls[...]/really_fit_in_one/field,then</code>

The field will look a bit nicer and still have useful information.

== Status ==

This code is in pre-epsilon status. Wait a few hours, or contact me if nothing happens in that amount of time [[User:Thunderrabbit|Thunder Rabbit]]
