RE: [PHP] PHP - class question
I would suggest you write a method (called mydb() for example) that connects to your database, and if needed, call it from your constructor like: $this-mydb(); This way you can always reuse the method from other code. hth, Steve. -Original Message- From: Mark Armendariz [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 14, 2002 2:44 PM To: [EMAIL PROTECTED] Subject: [PHP] PHP - class question Hello, To begin.. i'm new to the list...

Re: [PHP] PHP - class question
If you are just trying to access a classes functions without creating an instance of it you're probably looking to use the scope resolution operator ::. For this to work all you have to do is ensure that the definition for the class you wish to use is included into the file containing the class you are trying to call the functions from. You would then call the functions as follows: ClassName::FunctionName(); At 02:43 PM 8/14/2002 -0400, you wrote: Hello, To begin.. i'm new to the list...

Re: [PHP] PHP - class question
Well, I actually have a full db class which has a connect and close method
as well as query, fetch_array, etc... What I really want to know is how to
use the methods in my db class from another class (myclass for example)..
Do I include the db class from the myclass constructor and then set a
myclass variable = to the db object?
ie.
class my_class {
var $db;
function my_class() {
include('class_database.php');
$this-db = new database;
}
...
}
or is there a differnet or better way?
Thanks
Mark

Re: [PHP] PHP - class question
Do you know where I can find more info on how to use the scope resolution operator? My searches aren't giving much (at leant not mcuh regarding php) and in the manual, it only shows up momentarily as a note in the operators section...
