删除两个特定字符之间的逗号

Question

I currently have the string:

"Blah, blah, blah,~Part One, Part Two~,blah blah"

I need to remove the comma between the ~ character so it reads.

"Blah, blah, blah,~Part One Part Two~,blah blah"

Can anyone help me out please?

Many thanks,

If there is exactly one comma between the ~s and an even number of ~s in all, then

preg_replace("/~([^,]*),([^,]*)~/", "~\1\2~", $text) 

should do it.
