calling Class problem

skypilot

I am just trying a "class" structure for the first time and am missing something in the mix. The following is the code, and I am getting a parsing error on the include line of the calling php code.
Any idea what I am doing wrong?

Calling program:

<?php
include ('test.class.php');
$express=new_test();
print ("Returned value is: $express ");
?>

test.class.php:

<?php
class_test
{
var$filename;
function_test ()
{___
$filename = "WE WANT TO PRINT THIS";
}
?>

You're missing a curly bracket to close the class definition.

Sorry for the typo when posting. I fixed the script so that the class has a closing }......stil has a parsing error on the include line.

Any other suggestions?

could you c+p the error?
I would think that $express would just return an instance of the object.
I didn't think that php classes had constructors.. but I've not played with them at all. Try this:

Calling program:

<?php
include ('test.class.php');
$express=new_test();
print ("Returned value is: ".$express->testIt ());
print ("Returned value is: ".$express->filename);
?>

test.class.php:

<?php
class_test
{
var$filename;
function_testIt ()
{___
$filename = "WE WANT TO PRINT THIS";
}
}
?>

Remember the concept of encapsulation in OOP! The $filename variable should not be directly accessible from outside the class. So you should create accessors and mutators (sets and gets) for each variable you wish to modify from outside the class.

From within the class, any member variables are accessed with the $this keyword. See below:

test.class.php:

class test {
  var $filename;

  function test() {
    $this->filename = "PRINT THIS";
  }

  function getFilename() {
    return $this->filename;
  }
}

Calling program:

include_once("test.class.php");

$express = new test();
print("Returned value is: " . $express->getFilename());

oops.. forgot the $this..
those are concepts of OOP, but directly accessing a variable works still.
Us bad programmers need space to move around in too.
