regex - Regular expression for parsing CSV in PHP

Question

I already managed to split the CSV file using this regex: "/,(?=(?:[^"]"[^"]")(?![^"]"))/"

But I ended up with an array of strings that contain the opening and ending double quotes. Now I need a regex that would strip those strings of the delimiter double quotes.

As far as I know the CSV format can encapsulate strings in double quotes, and all the double quotes that are already a part of the string are doubled. For example:

My "other" cat

becomes

"My ""other"" cat"

What I basically need is a regex that will replace all sequences of N doublequotes with a sequence of (N/2 - rounded down) double quotes.

Or is there a better way ? Thanks in advance.
