This is my class code:
class myClass
{
public function myFunc()
{
$myvar = 'Test str';
}
public function result()
{
echo myClass::myFunc()->$myvar;
}
}
and I use this:
$nCls = new myClass;
$nCls->result();
To show Test str form myFunc() but nothing shown. I think the problem is :
echo myClass::myFunc()->$myvar;
Thanks for any help.
You are mixing up quite a few concepts.
First, you have to create a new object of class myClass:
$nCls = new myClass();
Then, you can call the member function (method) on that class:
$nCls->result();
In result(), you just call the other method using $this:
public function result()
{
echo $this->myFunc();
}
Note though that this does nothing. The variable $myvar is local and not a class attribute. I advise you read up on object oriented programming, and object oriented PHP in particular.
class myClass {
public $myvar;
public function myFunc() {
$this->myvar = 'Test str';
return $this;
}
public function result() {
echo $this->myFunc()->myvar;
}
}
$nCls = new myClass;
$nCls->result();
You can do this but this is not a good practice.
The problem is that you declare $myvar only in the scope of method myFunc(). That means it is not visible outside that method. Declare it as a class member instead:
class myClass
{
private $myvar;
public function myFunc()
{
$this->myvar = 'Test str';
}
public function result()
{
echo myClass::myFunc()->$myvar;
}
}
the problem is the scope, you can't call a variable within another function, define a property for the class and set it from a function then retrieve the property with result():
class myClass
{
public $myvar;
public function myFunc()
{
$this->myvar = 'Test str';
}
public function result()
{
echo $this->myvar;
}
}
include "views.php";
class Controller extends views{
function index(){
$this->head();
$this->home();
}
function privacy(){
$this->head();
$this->privc();
}
function about(){
$this->head();
$this->abt();
}
function address(){
$this->head();
$this->add();
}
}
$obj=new Controller();
if(isset($_GET['fun'])){
$obj->$_GET['fun']();
}
else{
$obj->index();
}
This is views.php code
class views{
function head(){
include "views/header.php";
echo "<br>this is header";
}
function abt(){
include "views/about.php";
echo "<br>This is about us page";
}
function home(){
include "views/home.php";
echo "<br>This is Home page";
}
function privc(){
include "views/privacy.php";
echo "<br>This is privacy page";
}
function add(){
include "views/address.php";
echo "<br>This is address page";
}
}
