phped 6.0 (6030), php 5.3.3, debug in HTTP mode(3rd party WEB server), ??? listener 4.0.5

example

$email = "";
$pass = "";
$token = '2f0895887121f6c783bbd0023b7a51e4';

$statement = $connection->prepare("SELECT email,pass FROM user_candidate WHERE token = ? LIMIT 1");
$statement->bind_param("s",$token);
$statement->execute();
$statement->store_result();

$nm = $statement->num_rows;
echo(nm);

$statement->bind_result($email, $pass);
$statement->fetch();
$statement->free_result();
$statement->close();



in run mode (Ctrl+F9, and in ext webbrouser) $nm return a 1, in debug mode( F9 ) $nm every return 0

Why ???

This code does not depend on debugger functionality and therefore results should not depend on whether it is executed with or without debugger.
First, please check whether you run the code agains the same database in the two cases -- with and without debugger
If the DB is the same but the values are different, it may be resulted from a bug in corresponding extension -- mysql driver for example -- you know such errors as uninitilized data? It's better to try newer php -- 5.3.8 for example.
