Hello, I want my preg_replace change all (multiple) spaces into one charachter | , EXCEPT those spaces that are inside quotes, but I can't find the right expression.  

Some examples:
testA testB testC testD            -->      testA|testB|testC|testD
testA "testB testC" testD      -->      testA|"testB testC"|testD
testA "testB testC testD"      -->      testA|"testB testC testD"
"testA testB testC" testD      -->      "testA testB testC"|testD

If possible also with the quotes gone, but I can do that with placing the quote in a second item of 2 arrays in preg_replace.

What I found so far is the following, but it's no good:
preg_replace ( array('/(?<![" ])\b(\s+)\b/','/\\\"/'), array('|','')

Help, I need somebody.  Help, not just anybody.  He-e-elp.  (Referring to the song ;-) )
