If you run the code it will return 'abcdef' not 'abcadaef'. You are correct that it does not preserve order though. The results are returned in alphabetical order.

The desired return string from your input (aabbccaaaaddaaeeff), would be: abcadaef The count_chars function only returns all the individual characters used without repeats and does not preserve order: abcdef Close -- but no cigar.

Therefore stripping any repetition is a bit too strict for my purpose. So I use this one to prevent chars repeated more than 3 times with any whitespace (prior to this, I strip any whitespace down to only one at a time): preg_replace('{( ?.)\1{4,}}','$1$1$1',$str); The info on this page was a great inspiration for this...
