I'm not sure what you mean, rproffitt?

It looks like he's looping through each row in the result set generated from query $q, and saving the row in an array $r for the iteration of the loop. That's what I do as well.

Line 7's call can have an object oriented or procedural style. While it looks like he's doing that, the line does not look valid to me.

This is why I supplied a link to the documentation.

I'm assuming mysqli query is returning false, hence the boolean msg.

OK, here's the example for the object oriented method.

$query = "SELECT Name, CountryCode FROM City ORDER by ID LIMIT 3";
$result = $mysqli->query($query);

/* numeric array */
$row = $result->fetch_array(MYSQLI_NUM);

Line 7 in the OP's source is incorrect in my view as the $q is well, unexpected. Should be an int, not the result from line 6.

While I like the oop method, I can't see anything wrong with the procedural code other than I'd enclose the whole thing in a conditional. As in if($q =....)

Then again if line 6 fails so will 7. OP needs to test for that.

Then again if line 6 fails so will 7. OP needs to test for that.

That was my point. I believe Line 6 is returning 'false'. From the manual on mysqli_query:

Returns FALSE on failure. For successful SELECT, SHOW, DESCRIBE or EXPLAIN queries mysqli_query() will return a mysqli_result object. For other successful queries mysqli_query() will return TRUE.

The OP is running a SELECT query so he/she either gets a result object or FALSE.

So I'm assuming $q is set to FALSE, and therefore cannot be a valid parameter for line 7. This is my rationale for using a conditional...

if($q = mysqli_query($con,"select * from packages")){
     while ($r = mysqli_fetch_array($q)) {
     ..etc..
     }
}else{
    echo "Failed";
}

You could also use try/catch.
