Answer 1

Your autocomplete.php file,

include('conn.php');
 $sql="SELECT * FROM oldemp";
 $result = mysqli_query($mysqli,$sql) or die(mysqli_error());

//Create an array
$arr = Array();
while($row=mysqli_fetch_array($result))
{
    array_push($arr,$row['name']);
}
header('Content-Type: application/json');
echo json_encode($arr)
?>

The result of this will be an JSON array which can be directly used in JavaScript. Hence, the script will be something like -

var availableTags = [];
$.ajax({
    url:"autocomplete.php",success:function(result){
    availableTags = result
}});
