PHP Echo Random Array and Insert to Database without repeat

Question

I have a code to roll a rand number, and show the winner based on their chance.

    $data = array();
    foreach($getAllUserTicketHistoryJson as $value){
                


        

Answer 1

for($i=0;$i<2;$i++)
{
  chance($getAllUserTicketHistoryJson[rand(0,count($getAllUserTicketHistoryJson))]);
}
function chance($arrWinner = array()){
 // the array for winner is
echo "
 Winner array ";
print_r($arrWinner);
echo "
";
}

try this... and if there is an errer... then let me know ... or add screen short of error if possible
