Answer 1

find: ",\s*" (without quotes)

replace with: " " (without quotes, just a single space)

or:

s/,\s*/ /g

Answer 2

Yuku's got it right. Here's in context:

preg_replace('/,\s*/', ' ', 'tag1, tag2,  tag3, tag4,tag5 tag6');

If some of your tags without commas between them have more than one space, you could use this instead:

preg_replace('/,\s*|\s+/', ' ', 'tag1, tag2,  tag3, tag4,tag5 tag6');
