My suggestion to PHP

Hello, Where can I get contact to the makers of PHP functions? I got a suggestion of new function which is very useful for storing array-data in a file, and faster than the old types. I have used explode() and serialize() before... but both functions got their own disadvantages, so i wrote my own function which is the fastest and practical way to store the data, and it does take less space than serialize (30% - 80% less space needed). It would be great, if the makers of PHP functions would even think of my suggest. Is there a place where I can give my suggestions to the function makers? Best regards, - T.M.
