Php code against template language

Next topic

Jean-Yves Zinsou	Thursday 26 February 2009 1:29:26 am Hi to all, Can someone explain why heavy computing is done faster when making a custom template operator that does the computing in php than when using template language? The template language is compiled and stored as php as well too so why is it slower ? I have seen many topics saying that heavy computing tasks should be done with custom operators.... Thanks to any one that takes a little time to answer this question. Do Androids Dream of Electric Sheep? I dream of eZpubliSheep.... ------------------------------------------------------------------------ http://www.alma.fr

If you write your own code you will probably try to make it as simple as possible which is often faster.

Hi,

If you write your own code you will probably try to make it as simple as possible which is often faster.
