[SOLVED] random array item chooser

[Q695]

I'm recieving the following error when choosing a random element from the following code:

Warning: array_rand() [function.array-rand]: Second argument has to be between 1 and the number of elements in the array

$creatures=array($rowc[id]);
$creature_num=mysql_num_rows($resultc);

$creature=array_rand($creatures, $creature_num);

How would I solve this issue?

$creatures will only be a single element long. What is $rowc['id']? If it's an array, you might mean to do...

 

$creatures = $rowc[id];

[Q695]

Now I get "First argument has to be an array".

 

I would need it to choose a particular random generator algorithm if it's an array otherwise it does this one.

Maybe you want to do this, just guessing though since I haven't seen any other code.

 

while($r = mysql_fetch_array($resultc)){
$creatures[] = $r['id'];
}

$creature = array_rand($creatures, 1);

 

But as genericnumber1 said, your $creatures array will only contain 1 element.

Thanks Fear, I also noticed that it was randomly ordering the creatures.
