Get 5 random values from an array?
And display them in alphabetical order.

PHP:

asort(array_rand($myarray, 5)); // for sorting values
ksort(array_rand($myarray, 5)); // for sorting keys

You can use sort() but it rewrites the keys

PHP:

asort(array_rand($videos, 5));

just returns the first 5 videos (ie: not choosing 5 random ones)

dunno, the function is array_rand, i use it quite alot.

try it without the sorts

PHP:

$arr = array('dog','cat','cow','horse','fish');
$rnd =(array_rand($arr,2));
echo $arr[$rnd[0]] . "<br/>";
echo $arr[$rnd[1]] . "<br/>";

then try this

PHP:

$arr = array('dog','cat','cow','horse','fish');
$rnd =(array_rand($arr,2));
foreach($rnd as $a){
	$temp[] = $arr[$a];
}
asort($temp);
print_r($temp);
