Enable error handler to mute expected messages

error muting is done because some people implemented custom error_handlers using
http://php./set_error_handler and for some reason did not understand the following paragraph:
It is important to remember that the standard PHP error handler is pletely bypassed for the
error types specified by error_types unless the callback function returns FALSE.
error_reporting() settings will have no effect and your error handler will be called regardless -
however you are still able to read the current value of error_reporting and act appropriately.
Of particular note is that this value will be 0 if the statement that caused the error was
prepended by the @ error-control operator.
Smarty deliberately uses @filemtime() over file_exists() and filemtime() in some places. Reasons include
- @filemtime() is almost twice as fast as using an additional file_exists()
- between file_exists() and filemtime() a possible race condition is opened,
which does not exist using the simple @filemtime() approach.
/

Enable error handler to mute expected messages

error muting is done because some people implemented custom error_handlers using
http://php./set_error_handler and for some reason did not understand the following paragraph:
It is important to remember that the standard PHP error handler is pletely bypassed for the
error types specified by error_types unless the callback function returns FALSE.
error_reporting() settings will have no effect and your error handler will be called regardless -
however you are still able to read the current value of error_reporting and act appropriately.
Of particular note is that this value will be 0 if the statement that caused the error was
prepended by the @ error-control operator.
Smarty deliberately uses @filemtime() over file_exists() and filemtime() in some places. Reasons include
- @filemtime() is almost twice as fast as using an additional file_exists()
- between file_exists() and filemtime() a possible race condition is opened,
which does not exist using the simple @filemtime() approach.
