catch an iconv E_NOTICE

i have this hack that works up to a point...

function my_err_handler($errno, $errstr, $errfile, $errline) {
if ( preg_match('/iconv/', $errstr) ) {
throw new Exception('iconv error');
} else {
// ? how to invoke default error handler ?
}
}
set_error_handler("my_err_handler", E_NOTICE);

try {
$s = iconv($enc1, $enc2, $s);
} catch (Exception $e) {
// deal with the failed conversion
}

but i'd like proceed with default error handling in the branch with the
question marks. how can i do that?

An error handler that passes through to the previous error handler:

error_reporting(E_ALL);

function my_error_handler($errno, $errstr, $errfile, $errline) {
restore_error_handler();
trigger_error($errstr, $errno);
}

set_error_handler('my_error_handler', E_ALL);

trigger_error('TEST', E_USER_ERROR);

You'll lose the file and line, though, because you're actually raising
another error with the same message at a new point in the code.

and i'd need to set my error handler back again to catch the next iconv
error:

function my_err_handler($errno, $errstr, $errfile, $errline) {
if ( preg_match('/iconv/', $errstr) ) {
throw new Exception('iconv error');
} else {
restore_error_handler();
trigger_error($errstr, $errno);
set_error_handler('my_error_handler', E_ALL);
}
}
set_error_handler('my_error_handler', E_ALL);

not lovely. as it stands, my own code writes the error message to the log
file in that place. i'm not sure this is an improvement.
