You don't need regex for this.

$output = explode(',', $input);
$output = array_map('trim', $output);
$output = implode(',', $output);

preg_replace('/\s*,\s*/', ',', $target_string);

Try this:

$output = preg_replace('/\s*,\s*/', ',', $str);

This will replace all commas with possible leading and trailing whitespace characters (\s) by a single comma.
