This sounds like a really simple question, but I am new to PHP. If I have a statement like this:

$r =& $db->query("insert into table (col1, col2) values (10, 20)");

Do I have to still execute it, or does it get executed when I reference it? I have another case where I have a select query, which seems logically to run only when I call fetchrow, but the code I am copying from does not call execute or fetch. I would have expected it to, so I cannot tell if it is just that I don’t get it, or that the missing execute statement is the problem. It also does not insert the record, but it does not throw an error I can find.

Also, I am a little confused by the =& notation. I looked it up on google, and found a few mentions of it, but I am still not clear on it.

Thanks.

    It will be executed when you call query()

    The =& notation is obsolete… it used to make the function return a reference to the resource object. But current versions of PHP (>5.0, I think) always pass (and return) objects by reference, so it doesn’t really change anything anymore.
