Smarty::muteExpectedErrors()

mutes expected warnings and notices deliberately generated by Smarty

Description
===========

string

muteExpectedErrors

muteExpectedErrors() registers a custom error handler using
[set\_error\_handler()](https://www.php.net/set_error_handler). The error
handler merely inspects `$errno` and `$errfile` to determine if the
given error was produced deliberately and must be ignored, or should be
passed on to the next error handler.

`\Smarty\Smarty::unmuteExpectedErrors()` removes the current error handler.
Please note, that if you\'ve registered any custom error handlers after
the muteExpectedErrors() call, the unmute will not remove Smarty\'s
muting error handler, but the one registered last.
