One way of doing that would be

like if have a unique ID to refer this quotes say u have 200 quotes and they have field say quote_id from 1 -200

u can use PHP rand() or srand() to select a number randomly and pass that to query.

I agree 100% with what Shivabharat advised. A few things I would add though:

With the more current versions of php you suppossedly don\'t need to seed rand with srand.

I would select min(quoteid), max(quoteid) from yourtable first, then use those values to pass to rand:

$randid = rand($minval, $maxval);

Then as Shiv suggested just do a select quote from yourtable where quoteid = $randid
