答
unix timestamp is an integer from 0 to n so you can just use the normal random method in php :)
$timestamp = rand(0, time() - 60*60*24*365*10);
// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A', $timestamp);
答
Get the seconds since the epoch for the two dates in question. Generate a random number between that range. Then convert back into a date.
答
$date = mt_rand(strtotime('-10 years'), time());
This will get you a unix timestamp, use date() to reformat it; and next time do the research yourself as this is a most basic question.
