Creating random number

[ZeroShade]

I need to create a random number and store it in a mysql database before the page is finished loading (as soon as possible). How should I go about doing this?

Uh... why?Anyway, you can just do it at the top of your page

$rand = rand(0, 100); //rand takes the range (min and max ) of the random numbermysql_query("INSERT INTO table (randomnum_field) VALUES ($rand)");

Thanks man!

i would like to know why?

For security reasons, maybe?E.g.* Generate random number, store to $rand* Store it to database* Include non-hotlinking page* Inside non-hotlinking page: -- Get random number $rand -- Retrieve most recent random number from db -- If $rand != random number from db then die(hotlink attempt) -- Else continue with execution* EndThat is one application I could think of...

it is funny you say that, i have no idea what a hot link is? lol

Hot link is a direct link to a file, so say if you had a file include.php, which was included in other files, but then if someone accessed it directly that would be hotlinking. Many hosts have provisions against image hotlinking due to bandwidth costs.
