How to merge classes & call it's variables?

[HungryMind]

Hi!I Have Two Classes & I Want To Merge Both Classes & Want To Use It's Variables.Please Guide.* index.php

require('config.php');$id = 'abc';$name = 'def';$email = 'ghi';A::f_A($id, $name, $email)

* config.php

class A{	function f_A($get_id, $get_name, $get_email)	{		$set_id 	= $get_id;		$set_name	= $get_name;		$set_email	= $get_email;	}}class B{	function f_B()	{		// I want to use index.php file variables here.		print $set_id . ", " . $set_name . ", " . $set_email;	}}

Why exactly do you need it this way? This is not a good practise in programming.You're attempting to use global variables. Usually if you're using global variables you should not have a class or function at all.

Thanks For Reply.Actually I've Code Like This:* index.php

require('config.php');$var1 = 'a';$var2 = 'b';$var3 = 'c';// Only First Time I Want To Send All These Variables To Classc_Default::f_Default($var1, $var2, $var3);// I Can Send All My Variables From This URL Class// But I Want To Use These Defined Variables From c_Default Classc_Element::f_URL();c_Element::f_IMG();

* config.php

class c_Default{	function f_Default($action)	{		$set_var1 = $var1;				$set_var2 = $var2;				$set_var3 = $var3;	}}class c_Element{		function f_URL()	{			   // I Want Use Those Variables Here From c_Default Class  			   // I can Use "global" Here, But! In Every Function I Have To Make Those Variables Global			   print "<a href=\"http://www.abc.com/index.php?var1=$set_var1&var2=$set_var2&var3=$set_var3\">Click Here</a>";	}		function f_IMG()	{			   // Once Again I Want To Use All Those Variables From c_Default Class			   // And I Don't Want To Make Those Variables "global"			   print "<img src=\"http://www.abc.com/$set_var1.png\" alt=\"$set_var2\" title=\"$set_var3\" />";	}}

All This Process I Can Create Using "global", But Someone told me that "global" is not a good practice if i'm making variables global again & again.Please Guide.Thanks a Lot.

Change the c_Element class to accept either the same variables or an instance of the other class. If you're only using static methods you might want to use functions instead of classes though.

$product = 'ebook';$id		  = '100';load_settings::__construct($product, $id); // How Can I Call __construct Here?class load_settings{	 public function __construct($get_product, $get_id)	 {		  $set_product = $get_product;		  $set_id		  = $get_id;	 }}class create_elements extends load_settings{	 function create_url($keyword, $url)	 {		  // I Want Use $set_product as 'ebook' & $set_id as '100' From __construct.		  // How Can I Call Variables From __construct function?		  // Look $set_product & $set_id Here, I Want To Call These Variables Here From __construct.		  print "<a href='http://www.abc.com/product.php?product=$set_product&id=$set_id'>$keyword<a>';	 }}Link 1: create_elements::create_url('Harry Potter');

You don't use constructors with static classes, normally the constructor gets called when you create a new instance:$obj = new load_settings();You also need to use the $this keyword if you want to set properties of the object.

	 public function __construct($get_product, $get_id)	 {		  $this->set_product = $get_product;		  $this->set_id		  = $get_id;	 }
