Hi Stefan, yes, this is exactly what I intend - I don't want to search in this field - just quicly return me the result in a serialized form (the search criteria is on other fields). Well, if I could serialize the data exactly as like the PHP serialize() does I would be maximally satisfied, but any other form in which I could compact the data easily into one field I would be pleased. Can anyone help me? I guess the <script> is quite a good way, but I don't know which function should I use there to compact the data to be easily usable in PHP. Or any other method?

Serializing (like http://php.net/serialize) your complete row into one field? Don't wanna search in them, just store and deliver them in your results? Does that make sense? Sounds a bit strange :) Regards Stefan On Mon, Jan 24, 2011 at 10:03 AM, Papp Richard <ccode...@gmail.com> wrote: > Hi Dennis, > > thank you for your answer, but didn't understand why you say it doesn't > need serialization.
