Help Understanding Classes

rulian

Okay Simple Problem


$thing=new A; 
$thing2=$thing -> B("wha"); 
Class A {

 function B ($obj){
 $bah=C($obj);
 }

 function C($string){
 Do stuff, return String
 }

}

give me function C not found, how do I call functions from within a class?
Are there any heirarycal relationship I need to be aware with classes, I dont have much experience with them and I want to start.

It may be that you're defining C after you provide a reference to it in $bah = C($obj);

You need to add a "this object" reference to the method call within the class, using $this:

Class A {

   function B ($obj){
      $bah = $this->C($obj);
   }

   function C($string){
      // Do stuff, return String
   }

}

I'm still going over using Classes with PHP myself. I've been coding procedural way too long... >.<

Can I have a class within a class for organization sake?
I'm trying but it's giving me errors. If I could rather then extend classes that would be great.
meaning

Class A {

  Class B{ 
  Bunch of Functions()
  Bunch of Functions()
  Bunch of Functions()
 } 

 Class C {
  Bunch of Functions()
  Bunch of Functions()
  Bunch of Functions()
 }





}

if so,
woudl it work liek so?

$myvar = new A;
$myvar = $myvar new B;
$myvar = $myvar - > Bunch of Funcitons()

No, class definitions cannot be inside of other class definitions.

You can create an instance of another class within a class's method, call static methods/attributes from another class, or (as you reference) extend another class. Which of those -- or some other solution I haven't thought of -- would be best would depend on what exactly you are trying to do.
