mysqli + xdebug breakpoint after closing statement result in many warnings

Question

I have a piece of code like this:

$conn = new mysqli($host, $username, $passwd, $dbname);

...

$stmt = $conn->prepare(\'SELECT ...\');
$stmt->bind_par         


        

Answer 1

There are some similar issues reported
http://bugs.xdebug.org/view.php?id=900

One way to get rid of this messages is to add

unset($stmt);

after closing the statement and before the breakpoint. If this does not help, you should also add

unset($connection);

after closing the connection as mentioned by @Martin in the comments.

This does not solve the problem itself, but let you go on with your work until this may be fixed some time.

EDIT: Now there is also a reported issue :)

EDIT: This seems to be a bug in the MySQLi driver as reported here.

EDIT: Looks like this bug does not appear if you use PDO. So this is maybe an other reason to switch to PDO.
