@Peter: the input condition was quite clear on that one: just commas. Replace the regexp with `"/,+\\s*/"` to also reduce whitespace to one space.

A:
$str = preg_replace('/,+/' , ',' , $str);
This will replace each sequence of one or more commas with one comma.

A:
preg_replace('/[,]+/', ',', $string); should do it... though depending on the nature of the input you may need a more complex expression.
