Array of objects

reverendmike

Hello. Here's what I'm working on. I have a database with calendar events, and before printing these events to the page, I want to store each event into an object, and each object into an array of objects. I understand the idea behind objects just find, but I just have problems using them.

The reason I want to use objects is that I'm going to use session and pass the objects to another document (in order to save myself from making another query to the database). I don't know how specific I'm supposed to go into, but basically what happens is that if they want to edit an event, they click the 'edit' button for that event and the event object (out of an array of event objects) with all its event object properties (ID, name, time, etc) are transferred to the edit page so that they can be displayed again (they'll be displayed in a form I already have set up).

But I think I'm getting ahead of myself. Right now I want to use my loop to read in each event (and the few properties with each event) into an object, and have all of those objects make up an array.

Thanks very much for help. This is my first time in one of these boards.

Do I need to give more information?

Are you writing the calendar to test your programming skills and further your knowledge of PHP? Or do you just need a calendar?

If the latter is the case, I'd recommend not reinventing the wheel and check out the PHPCalendar project on sourceforge: http://themes.freshmeat.net/projects/phpcalendar/

To further my knowledge of PHP.

I already made a calendar on my own, but now I'm re-doing it with objects, since with objects I can limit the number of queries to the database...

So if someone can help, please reply...

Sample code that doesn't so much:

class Event {
    var $name;
    var $date;

function Event($name, $date) {
    $this->name = $name;
    $this->date = $date;
}
}


$events = array();

$event1 =& new Event("Christmas", "December 25th");
$events[] =& $event1;

$event2 =& new Event("New Years Eve", "December 31st");
$events[] =& $event2;

The result of that is that $events is an array containing two instances of the Event class.

The =& is to assign the object by reference. Using plain = would copy the object (unless you're using PHP 5), which is almost never what you want.
