    class problem

    Hi,

    When executing the code below, expecting to say that the apple is green
    and later red I get the error

    Parse error: parse error, expecting `T_VARIABLE' in /httpdocs/test01.php
    on line 3

    Any idea how I can fix this?

    Thanks in advance,

    Roderik

    Code:
    <?php
class apple {
var color;

function apple() {
color = "green";
}
}

class banana {
var color;

function banana() {
color = "green";
}
}

var red_apple = new apple();
var yellow_banana = new banana();
?>

<html>
<head></head>
<body>
<?
print("The color of our apple is ".red_apple->color);
red_apple->color = "red";
print("Some weeks later the color of our apple is ".red_apple->color);
?>

</body>
</html>

      $color = "green";

      but doing so, $color will be a local variable.
      you want :
      $this->color = "green";

      And take some time to read the manual -- it may help.

          excuse me, I made very dirty code for the example now. I'll post a new
          one. The problem is still there.

              Hi,

              Here again the question with some more clear (but still errornous) code.
              I get the error:

              Parse error: parse error in /httpdocs/test01.php on line 10

              Any idea what the problem might be?

              Thanks in advance,

              Roderik

              Code:
              <?php
class apple {
var $color;

function apple() {
$this->color = "green";
}
}

var red_apple = new apple();  // line 10
//var yellow_banana = new banana();
?>

<html>
<head></head>
<body>
<?
print("The color of our apple is ".$red_apple->color);
red_apple->color = "red";
print("Some weeks later the color of our apple is ".$red_apple->color);
?>
</body>
</html>

                  Ow now I see, I am not commercially enough. I still forgot to place some
                  dollar signs. But it is fixed now.

                          s/var//
                          s/red_apple/$red_apple/

                          And definitively : RTFM !
