Php help needed.
 

Does someone know how you do this

I'd like to generate 10 random #'s 1 thru 100 and atleast a gap of 4 apart. None can be a duplicate of the other.

Anyone know how to do that?

Thanks

Yes, Pay me :1orglaugh

hmm basically you just need the rand(1,100) function and you test the result with your conditions...

:thumbsup sounds like a good algorithm to me

srand function go read on it at php.net

I'm lazy...it's 4am :thumbsup

I'm assuming he knows how to do while() with conditions...etc...if not then he needs someone to do the script...not some help with it..! ;-) then I could do it...but we get back to the previous point...it's 4am... i'm tired... LOL

ah, why pay someone, this script would be so easy, worth what 10 dollars...LOL...dude, he could learn the php while() command on php.net. easy to learn..

Okay this covers your requirements, gives you 10 randomly generated numbers, at least 4 digits away from any other number it previously gave you.

$uniq=array();

function four_or_more_apart($number,$array){
$keys=array_keys($array);
for ($x=0; $x<count($keys);$x++){
if ($number-4<$keys[$x] && $number+4>$keys[$x]){
return 0;
}
}
return 1;
}

while($counter<10){
$number = rand(1,100);
if (!$uniq[$number] && four_or_more_apart($number,$uniq)){
$uniq[$number]++;
print "$number\n";
$counter++;
}
}

Kind of curious what yah need it for though...

my beautiful contribution

I want to rotate in random sponsor galleries. I could just hardcode certain spots to be sponsors but I figured doing it random might improve my productivity? Plus new code always helps me somewhere else and I become better at php.

I appreciate the help and when I get going i'll test it out tommorow what was posted.

Thanks
