php dateformat to moment js format

I have got a config for php dateformats

'dateFormat'        => 'd.m.Y',
'timeFormat'        => 'H:i',
'dateTimeFormat'    => 'd.m.Y H:i',

But for the datetimepicker i need moment.js formatting (http://momentjs.com/docs/#/displaying/format/) that will look like so:

DD.MM.YYYY
HH:mm
DD.MM.YYYY HH:mm

This would be no problem for me to replace d with DD and m with MM but i was wondering if nobody before has built something to do this.

So i wrote a litte helper function to convert the php dateformats into the format needed for moment.js

function convertPHPToMomentFormat($format)
{
    $replacements = [
        'd' => 'DD',
        'D' => 'ddd',
        'j' => 'D',
        'l' => 'dddd',
        'N' => 'E',
        'S' => 'o',
        'w' => 'e',
        'z' => 'DDD',
        'W' => 'W',
        'F' => 'MMMM',
        'm' => 'MM',
        'M' => 'MMM',
        'n' => 'M',
        't' => '', // no equivalent
        'L' => '', // no equivalent
        'o' => 'YYYY',
        'Y' => 'YYYY',
        'y' => 'YY',
        'a' => 'a',
        'A' => 'A',
        'B' => '', // no equivalent
        'g' => 'h',
        'G' => 'H',
        'h' => 'hh',
        'H' => 'HH',
        'i' => 'mm',
        's' => 'ss',
        'u' => 'SSS',
        'e' => 'zz', // deprecated since version 1.6.0 of moment.js
        'I' => '', // no equivalent
        'O' => '', // no equivalent
        'P' => '', // no equivalent
        'T' => '', // no equivalent
        'Z' => '', // no equivalent
        'c' => '', // no equivalent
        'r' => '', // no equivalent
        'U' => 'X',
    ];
    $momentFormat = strtr($format, $replacements);
    return $momentFormat;
}
