Array of class object in another class

[sader]

I have two classes

class parent
{
   var childs = array();

   public function GetChilds()
   {
       //some stuff here
   }
}

class child
{
   var a;
   //bla bla bla
}

 

 

This is how I write it but something is wrong and it doesn't work. Is this "trick" possible with php?

It works, but if you are using php 5, you shouldn't use the var keyword, and if you are not you need a $ before childs

 

var $childs = array();

or

static $childs = array();

 

I am not sure if the second one is right, as I do not code in PHP 5, but if you are using PHP 4 I know the first one is right and you will probably have to remove the public keyword.

Do you mean something like:

 

class MainClass {

var $children = array();

function MainClass() {
$c1 = new Class1();
$c2 = new Class2();
$c3 = new Class3();
$this->children = array($c1, $c2, $c3);
}
}

class Class1 {
//some stuff here
}

//class2 and class3 below

 

 

That would work fine, but I don't know if it's what you meant.

If you are using php5 write "$var_here", if not write "var $var_here"

No, you'll use a visibility keyword (public, protected or private) instead the of the var keyword. var will still work in PHP5 though.

 

See: http://php.net/oop5.visibility

var is problematic if you have E_STRICT error reporting. But no one uses E_STRICT. E_ALL mostly but not E_STRICT. So you can use var without any prob.

An E_STRICT is not an error. It's just if PHP thinks you should do it in another way. It's perfectly valid to ignore E_STRICTs. You would for example have to use var if you are creating a script which is to be released and you want to ensure that it can be run by users whose host is using PHP4.

I try to stick with var simply because I'm lazy.

 

Oh!  And because I run PHP 5 locally, but I can never be sure what a web host will be running.
