RANDOM script
 

Hi, I am looking for a script ( PHP )

I want script to display 5 images out of 200, these 5 imasges must be unique ( no repeating )

I think the function "array_rand" must be used but Iam not that good to write a script

Thank you

Simple. i will give it to you in c++ pseudo-code.

int[] thePictureArray = new int[200];
int[] theSelectedArray = new int[5];

/* fill thePictureArray with your pics, or if they are numberd 1 - 200 skip this step */

int select = 0;
int randomNumber = 0;
for( select = 0; select < 5; select++ )
{

boolean needNewNumber = true;

while( needNewNumber )
{
needNewNumber = false;
/* pick random number 0 - 200 */
randomNumber = random(0, 200);

/* check to see if it is used */
int check = 0;
for( check = 0; check <= select; check++ )
/* compare the number you picked with the numbers you have used */
if( randomNumber == theSelectedArray[check] )
needNewNumber = true;
}

theSelectedArray[select] = randomNumber; /* or thePictureArray[randomNumber];
}

that shoudl do it.

Jesus Bret you make it seem as easy as washing your hands.. I expected to come in here and try and send a link to someplace... Nice!

the code may not be perfect. but i was not about to troubleshoot anything. if he can't figure it out from there. oh well. maybe read a book or something.

there are a lot faster ways to do it. but that way is the simplest to understand, i feel.

I'm impressed, that is amazing. :)

If it weren't 5am and I hadn't just spent the past 20 hours rebuilding my computer I'd post the actual PHP code to accomplish exactly what s/he wants.

It's going to use the mt_srand, mt_rand and a couple other functions but is pretty simple to implement.

Lemme get a few hours of sleep and I'll post the full code up for yas. :)

My Kingdom for a pillow and a fully functional computer...

Heres a quick one i did last week, its hard coded (naughty :)) and doesnt use a db but my host is a pain with not letting me do the db myself atm. But it does a random from the case, which you could adapt to use with a db. I use the variables to change the alt tag, img etc on a group of banners. Like i said it was just a quick fix.

$random = rand(0, 4);
switch ($random)
{
case 1:

break;

case 2:

}
?>


And put this where you need the variables:
