Php Scripting : Mysql Time format and PHP Calc based on opening hours in database

10 New Member
Hi people,

I'm working on a project where I have a MYSQL database containing a database table which has opening hours of a load of businesses in it.

Each business has 4 TIME fields for each day in the format 00:00:00 which are named to indicate the weekday i.e MONOPEN1, MONCLOSE1, MONOPEN2, MONCLOSE2, TUEOPEN1....... ..

My original idea was to output it as a table in the format

14:00-16:00.......... . obviously showing 4 times per weekday

I then found that I haven't got room for it on my webpage so I decided that the best way would just to give a visual indication as to whether the business is open or closed.

So I had to determine the day:

I managed that using the code:

Expand|Select|Wrap|Line Numbers
  1.  $timestamp = time();
  2.  $day = date("D",$timestamp);
  3.  echo $day;
I can use an IF statement to pick up the day and look at the respective 4 fields but heres what i'm really struggling with:

1. I want to format the times so that they are in the format HH:MM not HH:MM:SS as stored in the mysql database

2. Once I have managed to do that I would like to be able to compare the current time (which I can get using a similar function to the above) to the 4 time values and set another field to "Open" or "Closed" so I can echo it to the screen
I just can't get my head round how to do this as I'm not great with maths and time calculations have just got me totally confused, especially with 4 times to look at each time.

If anyone can help with this I would really appreciate it as I am very new to PHP and MYSQL and am only learning at the moment. I've trawled the web quite a bit to try and work out how to do this and there's so many functions I'm lost!

heres what i've come up with, maybe someone can suggest where it might not work or a better way of coding it?

Expand|Select|Wrap|Line Numbers
  1.               <?PHP   // this code determines what the current date and time is and compares it to the businesses opening hours (assuming that there is a lunch hour also

You can use this :

[PHP]$timeval = date('H:i');[/PHP]

This wil produce the time in HH:MM

In the mysql database define the field as "time" data type

Hope this helps
