Try using shuffle,

$products=array("1","2","3","4","5","6","7","8","9","10"); 
shuffle($products);
foreach($products as $v)
 echo $v;

You forgot the $ in count($products). As a result, the parser is treating it as the string "products", which has a count() of 1. Therefore, the rand() function returns zero or one, which in your original array correspond to "1" and "2".
