[PHP] Sorting and foreach of MultiDimensional Array failing
In the following code, I'm reading a variable set of random numbers into a
multi-dimensional array.
The first iteration runs properly, but when I get to my 2nd+ iteration, I
get the following errors;
Warning: Wrong datatype in sort() call in /home/usrlinux/WWW/pballs.php on
line 18
Warning: Invalid argument supplied for foreach() in
/home/usrlinux/WWW/pballs.php on line 19
Is there a specific function for sorting and foreach statements of
multidimensional arrays? If so, why does it work properly for the first
interation,i.e. sort($num_array[1]) then subsequently fail on
sort($num_array[2])
Thank you in advance!
?
srand ((double) microtime() * 100);
$totnum = 5;
$min = 1;
$max = 49;
$tickcount=1;
$num_array = array();
array_push($num_array, array());
echo Now Generating $tickets Tickets!br\n;
while ($tickcount = $tickets)
{
while ( $numbercount $totnum)
{
$num_array[$tickcount][] = rand($min,$max);
$numbers = array_unique($num_array[$tickcount]);
$numbercount = count($num_array[$tickcount]);
}
sort($num_array[$tickcount]);
foreach($num_array[$tickcount] as $val)
{
echo img src=ball.php?text=$valcolor=greynbsp;nbsp;
}
$pb[$tickcount] = rand(1,42);
print img src=ball.php?text=$pb[$tickcount]color=red;
$tickcount++;
}
?

[PHP] Random PowerBall Generator
More as an exercise to get back into the swing of PHP, I have created the PowerBall number generator. (for those of you un-aware, the powerball is at $200 mil). Took me a while to figure out using arrays, and the array_unique function. It also incorporate the imagepng function. Thanks to CC Zona for pointing me to the function I needed to get the job done! The page is at http://www.usrlinux.com/pball.php Source code is available for viewing. Suggestions on cleaning up code welcome. Enjoy! James ___ James C.

[PHP] Not allowing same value in array. Example requested
Can someone show me how I could walk through each value (a random number) in an array to make sure no 2 are the same? I'm basically just trying to generate a random number generator. I'm just looking to create 10 numbers, none of which can be duplicates.
