error muting is done because some people implemented custom error_handlers using

|
It is important to remember that the standard PHP error handler is completely 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.
