[preg_replace() with exclusions]

Hello Everybody!

 

I'm trying to replace such string: "Karcher HDS-C 7/11, 9/15, 8/15-E" with "HDS-C 7/11, 9/15, 8/15-E".

 

I use this pattern "/[^A-Z0-9\s\.\,\-\/\(\)]/" for preg_replace.

And instead of getting "HDS-C 7/11, 9/15, 8/15-E", I'm getting "K HDS-C 7/11, 9/15, 8/15-E" with leading K.

 

So my rule: leave only words (1+ letters) in uppercase, 0-9, special chars; exclude words (2+ letters) that contain lowercase (first letter can be uppercase).

 

 

More examples (input => output):

 

Karcher B 140 R Bp => B 140 R Bp

Yard-Man YM 84 M-W 31AY97KV643 => YM 84 M-W 31AY97KV643

 

 

How can I adjust my pattern to get it work?

 

 

Thanks in advance.
