'S' is the ordinal suffix for day-of-the-month only. about moment.php

[docksteaderluke]

Here's my test code:

$timestamp = strtotime("2014-01-02");
echo date("nS", $timestamp);    // month number
echo date("jS", $timestamp);    // day-of-month
echo date("zS", $timestamp);    // day-of-year
echo date("wS", $timestamp);    // day-of-week
echo date("WS", $timestamp);    // week-number-of-year

One last thing:
'DDDD' should convert to 'z' not 'zS'

Hey there.

Thanks for the note. I'll have a look for the correct transformations but that wont happen until next week. Would be great if you could figure out the correct formats and push them - in case you have some time.

I'll see what I can do. Unfortunately there aren't any ordinal suffixes for anything but the day-of-the-month in PHP (as far as I can tell) so they (the suffixes) may have to be dropped during the conversion.

echo date('dS M Y'); // 13th May 2014

Thats what u want, right?

[fightbulc]

Ah, I see. U want something like:

265th day of the year

correct?

[docksteaderluke]

Well, it's not so much that I want it but rather that Moment.js supports that and PHP doesn't so you can't convert between the two. The 'S' in PHP is for day-of-the-month ONLY. There are no ordinal suffixes for day-of-the-year. This means that the aforementioned conversions don't work.

[docksteaderluke]

But yes, it seems (as far as I can tell) getting something like:
265th day of the year
... is impossible in PHP using date formats.

You can do this with PHP.

If you know it's the 265th day of the year you want, you really only care about the 5 to get the correct S value.

To get "th" you can use:
date( 'S', strtotime( '2014-01-05' ) );

If you wanted to get an "st" you can use:
date( 'S', strtotime( '2014-01-01' ) );

Thats what we want then:

Perhaps I'm missing something, but that doesn't seem to solve the issue because we don't know what day it is. This issue is dealing with converting a moment.js date format string to a PHP date format string.
i.e.
Mo -> nS
The problem with this is that 'nS' won't give you the correct ordinal suffix (at least not always, see OP).

[fightbulc]

Ok, I am just shooting quickly here but we have to do some logic here.

If the user requests something with "o" I know that he wants some ordinal shizzle.
"Mo" goes for the ordinal month. So if we parse for these formats we know what we need to deliver and can simply service it, right?

"Mo" stands for month so we run in php "m" through the aforementioned function which would result in "05th" instead of only giving us back "05".

Again, I am really just going by feeling right now since I am busy with some other stuff.
Looks cool to me at the moment. What u think?

[docksteaderluke]

Yes, if you want ordinal suffixes for anything other than day-of-month you need extra logic. But that seems out of scope for the MomentJS.php class since it only handles format strings and not the dates themselves.

SO, with regard to the MomentJS.php class: what should these conversions be?

Moment.js	PHP
Mo	???
Do	jS
DDDo	???
do	???
wo	???
Wo	???
