[RESOLVED] Setting a Variable in a Class

[rowanparker]

Hello,
If i have a very basic class (for example):

<?php
class basic {
     function printme() {
          echo $me;
    }
}
?>

How can I change the value of $me by accessing the class like this:

<?php
$a = new basic();
$a->setme("the_value_of_me");
//I know I can do this by just making a function setme
$a->me="the_value_of_me"; 
//I want to do this but I do not know how.
?>

Did i explain that clearly enough?
Thanks guys.

class basic
{
   var $a = '';

   function printme()
   {
      echo $this->a;
   }
}

$test = new basic()
$test->a = "Hello, World!";
$test->printme();

Note that in PHP5, if $a is defined as "private" in the class, then this will not work -- a public method would need to be provided to set the value.

You would write:

class basic {
    function printme()
    {
        echo $this->me;
    }

function setme($me) {
    $this->me = $me;
}

var $me;
}

Of course, if we are to keep to the concept of encapsulation, then you would not access $me directly from the outside. This means that $a->me="the_value_of_me" would not be allowed. You can do this with PHP5's private keyword:

class basic {
    function printme()
    {
        echo $this->me;
    }

function setme($me) {
    $this->me = $me;
}

private $me;
}

Thank you very much.

Exactly what I wanted 🙂
