Classes

benbox

Hi,

Can anyone push me in the right direction for classes?

ive tried basic things like:

<?
Class Test {
var $variable ;
$this->variable = "hello" ;
}

print "$Test->variable" ;
?>

but it doesnt work....
is that the general idea for a class and/or how can it be fixed..

thanks
Ben

you should read into the concept of object orientation.

basically, a class consists of attributes (variables) and methods (functions). in a class there is no code (except var declarations) outside a method.

(simplified🙂 a php class must be instantiated and used from "outside", i.e. a "normal" script. there, you so something with your class(es) using only the methods that are offered by the class(es).

well I can't explain it here completely, but check out some articles in phpbuilder and the web in general; once you have the background knowledge, you'll like classes.

First, read up on what classes and objects are:

As for you example:

<font color=blue>
<?PHP

Class Test {

 var $myClassVar;

 function setClassVar($newVal) {
  $this->myClassVar = $newVal;
 }

}

$myObject = new Test;
$myObject->setClassVar("Hello");
print "$myObject->myClassVar";

?>
</font>
