I'm not quite sure what I'm doing wrong, but it appears I'm having myself a brain fry trying to comprehend it..
$cards = array(range(1,52));
shuffle($cards);
echo $cards[0];
I get a array to string conversion error.
I've also tried a custom function to echo dependent on the input value and that isn't working either.
The range function returns an array (http://php.net/manual/en/function.range.php), so the statement $cards = array(range(1,52)); has set $cards to be an array with exactly one element - an array containing the range of values from 1 to 52.
Thus when you try to echo $cards[0], you are trying to echo an element which is an array, which produces the error.
What you want to do is this:
$cards = range(1, 52);
shuffle($cards);
echo $cards[0];
Get rid of the array, range returns an array:
$cards = range(1,52);
Range already creates an array. You have create an array with one element that contains the array.
$cards =range(1,52);
shuffle($cards);
echo $cards[0];
