PHP meckert beim vorbelegen von variablen

[Axel Richter]

Hallo,

Oder: Richtige Syntax, falsche Sprache.
$reply_to="webmaster@".$_SERVER['SERVER_NAME'];
nicht ganz.... ich hab das ja innerhalb einer klasse stehen.
und da müssen variablen meines wissens mit einem "var" deklariert werden, oder?

In PHP 4, only constant initializers for var variables are allowed. To initialize variables with non-constant values, you need an initialization function which is called automatically when an object is being constructed from the class. Such a function is called a constructor (see below).

<?php
class Cart {
   /* None of these will work in PHP 4. */
   var $todays_date = date("Y-m-d");
   var $name = $firstname;
   var $owner = 'Fred ' . 'Jones';
   /* Arrays containing constant values will, though. */
   var $items = array("VCR", "TV");
}

/* This is how it should be done. */
class Cart {
   var $todays_date;
   var $name;
   var $owner;
   var $items = array("VCR", "TV");

function Cart() {
       $this->todays_date = date("Y-m-d");
       $this->name = $GLOBALS['firstname'];
       /* etc. . . */
   }
}
?>

viele Grüße
