PHP Class variable access question.

I'm having trouble accessing a class' variable.

I have the functions below in the class.

class Profile { 

    var $Heading;

    // ...

    function setPageTitle($title)
    {
        $this->Heading = $title;
        echo 'S: ' . $this->Heading;
    }

    function getPageTitle2()
    {       
        echo 'G: ' . $this->Heading;
        return $this->Heading;
    }

// ...
}

Now when I run the method $this->setPageTitle("test") I only get

G: S: test

What's wrong with the getPageTitle2 function? Heading is public btw. Please help!

Thanks guys!

From stackoverflow Fergs

• you have to declare the Heading and title out of the function ... i dont know if you already did that

  see the order of calling the functions

  Fergs : yes, my class starts like: class Profile { var $Heading; but does $title need to as well even though its feed straight into the function?

  antpaw : no its a anonymous variable

• If you have "G: S: test" it means you called getPageTitle2 before setPageTitle ! It looks normal then : I suggest first set then get.

• Now when I run the method $this->setPageTitle("test") I only get

  G: S: test

  That sounds implausible. Are you sure you're not running:

  $this->getPageTitle2();
  $this->setPageTitle("test");
  

  PHP - like most programming languages - is an imperative language. This means that the order in which you do things matters. The variable $this->Header is not set at the time where you call getPageTitle2.

  cballou : sounds likely to me..

  Fergs : well i have other functions //(the only one that calls the set function) function getPageContents() { $this->setPageTitle("test"); } and the other function setContent // runs the getPageTitle2 { echo '

  '.$this->getPageTitle2().'

  '; } so i didn't think it mattered the placement of functions within a class. Perhaps the getPageContents() must be placed above the Set()?

  meagar : @Fergs Placement of the method in the class doesn't matter, this I can guarantee. Somewhere in your code, you are explicitly calling getPageTitle2(), before you call setPageTitle() - there is no implicit or otherwise automagical way to call a method named getPageTitle2.

  Fergs : thats what i figured: i;ve uploaded the code to www.fearghal.com/Untitled-1.phps Its semi large but the SetContent and getPageContents are in there and call the functions in question...could you have a look?

  troelskn : @fergs That code is just a class. It won't do anything at all. Your problem likely lies in the code that *uses* the class.
  From troelskn

• class Profile {

  var $Heading;
  
  // ...
  
  function setPageTitle($title)
  {
      $this->Heading = $title;
      echo 'S: ' . $this->Heading;
  }
  
  function getPageTitle2()
  {       
      echo 'G: ' . $this->Heading;
      return $this->Heading;
  }
  

  // ... }

  I am guessing you are doing something like this:

  $profile = new Profile();

  $profile->setPageTitle("test"); $profile->getPageTitle2();

  and that this would result in the following output:

  S: testG: test

  and that if you echo $profile you will just get

  test

  so what do you think is the problem or what are you not accomplishing that you want to?

  also I would probably declare $Heading as

  private $heading;

• If I'm not mistaken you're asking the same question as one I asked a few months ago. http://stackoverflow.com/questions/1618766/php-class-arguments-in-functions Should get you what you want!

  Hope I helped
