mysqli_fetch_array's 1st parameter must be a result of a query. what you are doing is you are you are passing the connection(which doesnt makes sense) and the query command itself.

read the doc here: http://php.net/manual/en/mysqli-result.fetch-array.php

to fix this, execute the query first, then store the result to a variable then later fetch that variable.

$sql = "select * from privinsi";
$result = mysqli_query($connection,$sql);
while($r = mysqli_fetch_array($result)
{
    /// your code here
}

You write sql query but didn't execute.

$sql = "select * from privinsi";
$results = myqli_query($connection,$sql);
while($r = mysqli_fetch_array($results){
   //enter your code here
}
