Re: Random query question
If you are using MySQL as your database backend, read http://www.desilva.biz/mysql/random.html (found by Googling mysql random row). If you are not using MySQL, check if your database has a similar function. On May 19, 5:56 am, Sarpidon epap...@gmail.com wrote: Hi everybody.

Random query question

Re: Random query question
one simple way would be to fetch all the records, then generate two non-equal random numbers in the range of found records, then pluck those two out of the result array. The returned records are numbered 0-10 in that array so it will be very simple to do! http://us.php.net/manual/en/function.rand.php Regards, Don On May 19, 5:56 am, Sarpidon epap...@gmail.com wrote: Hi everybody.
