include file in class

[Carramba]

hello!

Iam wondering how can I include file in class? is it possible?
is it possible to create object inside another object? for instance if I
create mysqli connection object inside another class is that doible? or
one should pass created objekt as parameter to another objekt?

regarding include it works if I do like this
PHP Code:
class myClass{
function(){
include 'func.php';
func(); //returns $var
//do something with $var
return $array;
}

function1(){
include 'func.php';
func();//returns $var
//do something with $var
return $array2;
}
}

but it doesn't make eny sence to include it over and over again in every
function so I would like to that get some thing like
PHP Code:
class myClass{
include 'func.php'; //but this don't work
func(); // $var=3

function(){
//do something with $var
return $array;
}

function(){
//do something with $var
return $array2;
}

any ideas or comments?

thanx in advance

Yes, but if you'd bothered to try it out you'd have found that although you
can include within a class/function/condition/loop the included code is
included in the global scope.

I suspect it may be possible to achieve the result you want but it's not
overly clear from your post what that is.

That's where you can use the constructor for:

class myClass {
var $var;

function myClass() {
include 'include.php';
$this->var = getVar();
}
}

However, keep in mind that this is not a very good OO design. If you have a
collection of utility functions, the best way to use them is through
static/instantiated method calls or through inheritance:

Example A (static calls):

include 'Utils.php';

class myClass {
var $var;

function myClass() {
$this->var = Utils::getVar();
}
}
Example B (inheritance):

include 'Utils.php';

class myClass extends Utils {
var $var;

function myClass() {
$this->var = $this->getVar();
}
}

thanx!

It seem to pass an object from a function one should declare

include 'somefile.php'; //have getObj() with returns object

class myClass {
var $var;

function myClass() {
$var = getObj();
}
}

then I was trying to use $this->var I ll only get error about unknown
variable var

Thanx again

Using: $this->var would be correct. When this triggers errors, the getObj()
function should be examined.
