其他意想不到的？ [关闭]

Question

I tried this same coding in several ways, and none of them work.

public function getCalendarById($calendarId)
{
    $calendarsList = $this->getCalendarsList();
    if($calendarId == "1") {
        return $this->getMergedCalendars();
    } else {
        return (array_key_exists($calendarId, $calendarsList) ? $calendarsList[$calendarId] : null);
    } else {//******** error here ***********
        return (array_key_exists($calendarId, $calendarsList) ? $this->holidayrize($calendarId) : null);
    }
}

The error happens in the commented line. It says Unexpected T_ELSE

Any ideas why?

Yes, the syntax is wrong. You can't have multiple else clauses in a single if statement.

You can use elseif instead:

if($calendarId == "1") {
    return $this->getMergedCalendars();
} elseif ( /* second condition here */ ) {
    return (array_key_exists($calendarId, $calendarsList) ? $calendarsList[$calendarId] : null);
} else {
    return (array_key_exists($calendarId, $calendarsList) ? $this->holidayrize($calendarId) : null);
}

or a switch statement, if you're expecting more options.
