RegEx for PHP preg_replace swapping matches and matching multiple instances -


i'm looking regex preg_replace in php following scenario:

  • example string "bjerre- jonas, jorgensen- silas, wohlert- johan, madsen- bo"
  • desired string "jonas bjerre, silas jorgensen, johan wohlert, bo madsen"
  • string csv field , double quotes enclosures , part of string
  • any number of occurrences may exist including none - example has 4
  • there consistent - match on separating matches swapped

i'm noob @ php , regex , have been playing around in cool test arena things preg_replace("/^\"(?<=- )/", ""$2 $1$3"", $input_lines); horrible results. help!
