Adding to an array

[b1011]

You know how you can do this:

array("#ff0000","#ff8800","#0022ff","#33ff33")

 

Well how could i set it up so that in a while statement it adds to the array? And if its possible how can i make it add a random color (#ff0000 etc.);

Any ideas?

Did i explain good enough?

Well there has to be some sort of pattern to the array. And yes, if there is you can make it into a while loop.

<?php 
$colors = array('#ffff23', '#faaf23', '#ff3323', '#f99f23', '#ff8823', '#fff773'); 
?>

 

Then you call it by $colors[position] the position is the spot ur value is in so if u want #ffff23 it would be $colors[0]

Adding to the array is as simple as doing $array[] = $var. There's a few examples in the user comments on the php site for the mt_rand function for random hex codes. Ive used one for this example:

 

<?php
$array = array("#ff0000","#ff8800","#0022ff","#33ff33");
for($x=0;$x<9;$x++){
    //thanks to zolaar at nothanks dot com - taken from the a comment on http://uk3.php.net/mt_rand
   $num = mt_rand ( 0, 0xffffff ); 
   $output = sprintf ( "%06x" , $num ); 
   $array[] = '#'.$output;
}
print_r($array);
?>
