Bug #75964 [Opn->Fbk]: mysqli::query emits php warning instead of throwing an exception

There is a difference between mysqli and engine errors, though. For instance, when an array is passed to mysqli_query(), the engine raises a warning. An empty string falls into the same category of errors (although the warning is raised by mysqli). So, this example doesn't qualify as bug. There may be cases which shoud throw an exception instead of raising a warning; can you please try to come up with some way to reproduce those?

But even with corresponding settings made by using mysqli_report, \mysqli::query() is not throwing an exception but is emitting a PHP warning. This makes it very hard to handle the issue locally as the emitted PHP warning is hitting the PHP error handler instead of a local try-catch block. I am facing the issue with a mysql transaction deadlock/conflict right now, but it can be reproduced easily with an empty query, see test script and actual result. mysqli should honor the settings made by using mysqli_report for all kinds of error. Test script: --------------- <?php mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT); $mysqli = new \mysqli('<host>', '<user>', '<pwd>', '<database>'); // replace <host>,.. with connection settings $mysqli->query(''); Expected result: ---------------- PHP Fatal error: Uncaught mysqli_sql_exception: mysqli::query(): Empty query in /vagrant/test.php:5 Stack trace: #0 /foo/test.php(5): mysqli->query('') #1 {main} thrown in /foo/test.php on line 5 Actual result: -------------- PHP Warning: mysqli::query(): Empty query in /foo/test.php on line 5 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75964&edit=1
