________________________________________ i would like to display on my web application, the latest 3 events added to my web DB. something like latest 3 event which happen to company.
what is the best way knowing that each event is translated in several languages and stored into DB ? should i directly read latest 3 events from DB using PHP ? should i firstly query DB for each language, store the result into a txt file (for example) and after using AJAX or PHP read this file ? what do you use usally ? If you can figure out the SQL to do it, that is almost always faster. Even if you have to do 2 queries, hopefully simpler ones, it's still faster. Relative Expense Operations: EXPENSIVE | Opening DB Connection (possibly not on localhost, possibly over socket versus TCP/IP stack moves it down a level) | Opening local file | PHP loop through many many values | Complicated DB "JOIN" with many many rows | PHP loop through small number of values | One more small simple DB query CHEAP Of course, you can make a mess of this with extremes like a very very very remote DB, or a 486 DB server with an 8-cpu 64G RAM webserver or something "forced" to prove me wrong. And, of course, "many" could mean different things on different hardware; You have to be comparing on the same hardware, or it all goes out the window. But the above is a general rule of thumb. Hope that helps. It sure would have been useful to me in the first few years of my PHP programming :-) _______________________________________________________ The information in this email or in any file attached hereto is intended only for the personal and confiden- tial use of the individual or entity to which it is addressed and may contain information that is propri- etary and confidential.
