How can I convert month name to month number in php without using an array? Is there any inbuilt function available in php?

Eg: If I use "January" from the variable, it should change to "01".

$monthName = 'January';
$date = date_parse($monthName);
$monthNumber = $date['month'];

Note that this will return 1, not 01, so change your display format accordingly.

Add this for formating: `$monthNumber = ($monthNumber < 10 ? '0' : '') . $monthNumber;` – js-coder Jan 09 '12 at 13:59

Or `$monthNumber = substr("0$monthNumber", -2);` or `sprintf()` or ... – hakre Jan 09 '12 at 15:13

I'd do something like this as there are no Enum in PHP as far as I know.

class Months
{
    const January  = 1;
    const Feburary = 2;
    // etc.
}

var $currentMonth = Months::January;
