Re: Speeding up PHP?

First of all, you should break the results into chunks getting 20-30 results at a time. A page displaying 1275 result is anything but readable. Use LIMIT in your SQL query and create a navigation bar. Also use indexing of the columns and filtering (WHERE conditions). --- Andrei BEJENARU - Developer InterAKT Online http://www.interakt.ro/ Tel: +4021 312.53.12 Tel/Fax: +4021 312.51.91 "George Pitcher" <george.pitcher@ingenta.com> wrote in message news:AMEPJAJDOFCDLPGFDOIFEEDDCLAA.george.pitcher@ingenta.com... > Hi, > > I've started redesigning a website that is currently running using > Filemaker/Lasso.
