dBase Funktionen

I know lots of you dosent really use dbase, but i've builded a class to help the one how dose.(sorry for bad english)- dbase.php<?phpset_time_limit (0);// site_path defined by parentrequire_once (SITE_PATH.

some of you contacted me about memo fields and my script, so i'll just post my answers on the common question here.(note: this is not an adv for any program, only what i used for myself, and it's free)so, there are 2 options if you want to create/read memo fields:1. use a library for java/c++/c# to build a bridge between php and dbf file. i've used dbf2java. althougth it's not near complete as my other option, it's a good start. (http://code.google.com/p/dbf2java-library/)2. use an external program with pipes to grab the output. i used cdbflite, (http://www.whitetown.com/cdbflite/). it's free, and pretty much gives you everything you need to handle those dbf files. i'm not sure about big databases and it seems you need to register/buy it, but it's again, a start.hope it helps some of you who needs to handle those database files,Good luck,idan
