1. Remove any variable that contains big object if its not necessary. 2. Use unset when applicable 3. Read chunk by chunk. 4. Profile it to find the exact place where you are wasting memory. Optimizing that little portion of code can improve memory performance. -- Shiplu Mokadd.im My talks, http://talk.cmyweb.net Follow me, http://twitter.com/shiplu SUST Programmers, http://groups.google.com/group/p2psust Innovation distinguishes bet ... ...
