Question

I was wondering, if I have some code such as:

$result = $db->query($sql); // dont worry, its escaped
$myData = (array)$result->fetch_assoc();  

where

$result->fetch_assoc();

returns a mysqli result object.

Is casting it like this right away good practice? I would imagine this is an expensive call – is this true?

It sure makes things convenient to use immediately after I query for it, but I want to make sure I’m not doing something in bad form.

Thanks for any input,

According to the mysqli documentation it returns an array anyway…
