Still following and loving your PHP courses! Any chance you could create a tutorial on how to build an up-to-date website, with a login system and a members area? I cannot find ANYTHING online that is up-to-date on how to do this with PHP.

Joy Bhalla says:

I have a doubt,we could’ve used if else statements to determine the day,for example if $dayofweek == 5 or 6,i’m not saying this method is wrong,i just want to know why we did not use the alternative.

Caged says:

$dayofweek = date(‘l’);
“Today is $dayofweek”;

zed 0 says:

Haha same here, it’s Friday

Esmail EL BoB says:

its local time or server time ?

Frank Pacheco says:

Even though today(7/16/18) is Monday, the date() function states that it is Tuesday. Any thoughts as to why? Does it have anything to do with GMT? I live on the East Coast of the US.

ScreenPrintR says:

Actually forgot that you mention it was Friday. So I added the Page tags

to Friday, and not Monday of which it is today. After adding the P tag to each day it worked as yours does.

Slow Easy English says:

Hey mmtuts (sorry, I don’t think you say your name in any of the vids I’ve seen LOL).

First of all, I wanna say how excellent your tutorials are. I’ve only watched the PHP ones so I can’t speak for the others, but these are amazing. You know how many “tutorials” out there fail to explain things properly? 99%. Yes, 99%. You know how many fail to actually show you HOW do to things? 99%. Yes, 99%. You know how many fail to show you HOW to do things && explain them well? Yup. You are in the 1% of the 1%. It’s such a shame you’re not getting more views on these. With the quality of your presentation, I expected to see views of 50k+. Keep at it, man. Word will get out and they will pay off eventually. There is a serious shortage of quality instructors on the net so it’s only a matter of time.

After all that, I do have a question. LOL

When I did this, I got “5” for Friday. But it’s Thursday. So I tried “d” and I got “02”, but it’s December 1st, not 2nd. My first thought was that maybe my server is in a different time zone. Oh no, I’m using localhost on WAMP. lol. Could my VPN be responsible? Shouldn’t. I’m connected to New York right now and it’s the same time there as here. Check system time and date and it’s all accurate.

So what could be causing the date(“w”) function to be returning the wrong result?

Laxman Giri says:

Please upload on ubuntu OS too…U are very good teacher

Victor Rodriguez says:

it would have being better to use an array insted. Like this:

$weekday = array(“Sunday”, “Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday”, “Saturday” );
$dayofweek = date(“w”);

echo “Today is “.$weekday[$dayofweek];

ogün Kara says:

I’m definitely sharing these with everyone man, kudos to you

Aybars Öztürk says:

man u are god

ta22stcoupe says:

Very unnecessary way of figuring day of the week out. The date function has that already built in. Just do: < ?php echo date('l');?>

Will the says:

In atom opened new .less stylesheet is that ok or how do i make a .css one?

Jeroen Koorenhof says:

Thanks for this. Now having this running WITH a background :). I’m currently following the whole course. Although i’m familiar with the basics, there might be something i didn’t know!

Keep going with this. It’s very n00b friendly and i’m enjoying this content.

Enis Gusinac says:

Jacky Wong says:

i think may be use array to do this is better

Joan Ricart says:

It’s Tuesday!

sharifa bahar says:

Thank you . Your video make me to be alive with my job. I have a question that What did you use for style is it java script or css ?

G V says:

If there are more than one files in phptutorials (as in yours) then how can it work??

demian says:

You can just do:
< ?php echo "

This is “.date(‘l’).”“;

Amber Adams says:
