Description:
------------
If you use a set_error_handler() or register_shutdown_function() inside and (auto_prepend_file = "file.php") unusual behaviors such as register_shutdown_function() will not work on fatal error as well as the set_error_handler() will pass errors/warnings incorrectly to the function receiving the error. If you don't use the auto_prepend_file and place the code in say your index.php file and create an error the code will work fine

[.user.ini]
auto_prepend_file = "C:\IIS\Sites\site\test\log.php"

Test script:
---------------
 function myErrorHandlerr($errno, $errstr, $errfile, $errline, $error_context) {
	 $servername = "localhost";
	 $username = "root";
	 $password = "Tashia123";
	 $dbname = "log";

	 // Create connection
	 $conn = new mysqli($servername, $username, $password, $dbname);

	 // Check connection
	 if ($conn->connect_error) {
	     die("Connection failed: " . $conn->connect_error);
	 }

	 // prepare and bind
	 $stmt = $conn->prepare("INSERT INTO error_logs (error) VALUES (?)");

	 $errorssssss = $errstr.$errfile. $errline.$errno . json_encode($error_context);
	 //
	 $stmt->bind_param("s", $errorssssss);

	 // echo $errline;
	 $stmt->execute();

	 $stmt->close();
	 $conn->close();
     }

     function shutdownHandler() //will be called when php script ends.
     {
	     $lasterror = error_get_last();
	     switch ($lasterror['type'])
	     {
	         case E_ERROR:
	         case E_CORE_ERROR:
	         case E_COMPILE_ERROR:
	         case E_USER_ERROR:
	         case E_RECOVERABLE_ERROR:
	         case E_CORE_WARNING:
	         case E_COMPILE_WARNING:
	         case E_PARSE:
	             $error = "[SHUTDOWN] lvl:" . $lasterror['type'] . " | msg:" . $lasterror['message'] . " | file:" . $lasterror['file'] . " | ln:" . $lasterror['line'];
	             myErrorHandlerr($error, "fatal",'','','');
	     }
     }


     // Set user-defined error handler function
     set_error_handler("myErrorHandlerr", E_ALL | E_STRICT);


     register_shutdown_function("shutdownHandler");

Thanks for the report. Could you please clarify, what exactly is incorrect? Fe i use an index.php containing "$x = 1/0;" and set your code with a small modification to write into a file as auto_prepend_file in .user.ini. It creates a log file where i see

'Division by zero' 'E:\local_programs\nginx\html\bug75323\index.php' '5' '2' {"_GET":[],"_POST":[],"_COOKIE":[],"_FILES":[]}

which all seems correct.

Thanks.
