Re: [PHP] class effeciency
Hi
I too suggested a way for your previous problem.
What you are doing is right here, but some corrections are there.
You cannot use 'var' to declare variables inside constructors
rather you could use them only before constructor, and intialize
them inside constructor, look out the below code.
?php
class form
{
var $lang ;
function constructor($language)
{
$lang = $language
//.. other stuffs
}
}
In addition you can't intialize them too before constructor.
I hope it will work for you.

Hi all,
I have an application that spits out a contact form in either English or
Danish. Someone suggested I use a 'class factory' like the PEAR db
abstraction layer and that is what I'm doing.
So I choose the language like this:
$form = Form::GetFormObject($lang); //different class for each lang
No problem.
My question is related to the efficiency of this.
It is only the *properties* that are different in each language class
not the methods so I'm including all the same methods twice! That
doesn't seem terribly efficient.
I thought maybe I could init properties with a constructor in a single
class like this:
?
function test($lang) {
if($lang==en) {
var $lang=English;
} else if($lang=dk) {
var $lang=Danish;
}
}
}
?
But it fails.
Is there a better way? It just seems like overkill to include 6-700
lines of methods /twice/
Many thanks
