Class not working

[SCook]

I am having trouble with classes.  Here's a very simple class I made as a test, and the error message I get:
[code]
class dog {
  public function bark() {
      print("Whoof!");
  }
}
[/code]

And when I instantiate the class:

$dog = new dog;
$dog->bark;

and run it, I get this:


Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/ow1206/public_html/admin/class.class on line 4


Everything seems to be fine, but I just can't get it ro run, even with dot notation, and so on.  Any help would be great.

isnt it supposed to be

$dog = new dog;
$dog->bark();

Are you running PHP 4 or 5?  PHP 4 doesn't support public / private member data or methods.  Also, kobmart is right calling
[code]
$dog->bark;
[/code]
Is actually trying to reference member data of class dog named bark instead of the method "bark()".

Best,

Yeah, that was it.  Stupid php 4 and up.  That really throws off my OOP, which I why I really haven't used classes before.

Don't let PHP4 discourage you from writing OO code.  I'd guess that > 90% of the code I've written professionally has been OO PHP4.  Your class example can be easily rewritten to work in PHP4:

[code]
<?php
class dog {
  function bark() {
      print("Whoof!");
  }
}

$dog = new dog();
$dog->bark();
?>
[/code]

Best,
