Convert Numeric Month to Name Problem

[mickeymouse]

$mydt=$mymm.','.$mydd.','.$myyr;
print("$mydt<br>");  ------------------>= 1,1,2020
$myjd=gregoriantojd($mydt);
print("$myjd<br>");  ------------------>= blank (why???)
$myname=jdmonthname($myjd,0);
print("$myname<br>");  ---------------->= blank (why???)

W3 Documentation:
$jd=gregoriantojd(1,13,1998);
echo jdmonthname($jd,0);  ------------>= Jan

It seems to me my code agrees with the documentation but it doesn't work.

You're passing a single string into gregoriantojd() but it expects three integers.

I thought I was passing 3 integers via $mydt because it contains "1,1,2020"

I've made the change to pass 3 integers ($mymm,$mydd,$myyr) and it works fine.

Many thanks,

Mickey
