this code will not load on my localhost, but gives no errors. Will you load this and see if it will work:

<style type="text/css">
<?php

$count = 1;

function divs() {
    
      $int = rand(6, 30);
      
      while ($int <= 31) {
    
        $t = rand(1, 99);
        $l = rand(1, 99);
        $w = rand(2, 7);
        $h = rand(0.25, 1.25);
        
        if( rand(0, 1) == 0) 
            $col = "000049";
        else
            $col = "99ccff";
        
        echo ("div#d".$count." {position:absolute; top:".$t."%; left:".$l."%; width:".$w."in; height:".$h."in;");
        echo ("background-color:#".$col.";}");
        
        $count++;
    }

} 

function implement() {

    while ($count != 0) {
    
        echo ("<div id=\"d".$count."\"></div>");
        $count--;    
    
    }
}
 
?>

    <?php
        divs();
    ?>

Not tried the code, but it may be the scope of your $count variable thats the problem.

Both the $count in implement() and in divs() is not the same as the global $count variable declared above it.

thanks so much for helping. i've been working on this hours, and earlier i had gotten it right, somehow..

Is it working now?

You have two infinite loops, firstly the $int will always be less than 31 because you are generating a random number between 6 and 31.

And the second WHILE loop, $count will never not equal 1. Because $count is equal to nothing inside the function, look at this for example: -

<?php

$count = 1;

function test()
{	
	echo($count);
}

test();

?>

It outputs nothing.......

But this outputs 1: -

<?php

$count = 1;

function test()
{	
	global $count;

	echo($count);
}

test();

?>

Using "global" for you should sort out the problem as demostrated by this code that outputs 2: -

<?php

$count = 1;

function test()
{
	global $count;
	
	$count++;
}

function test2()
{
	global $count;

	echo($count);
}

test();
test2();

?>

However you need to sort out the first $int WHILE loop problem first.

There are a number of ways you can achieve the same thing, by either passing $count in the functions parameters, returning the new $count value from the functions, or by using the "global" syntax like as shown in the above examples.
