Error, but not sure why?

[mattspriggs28]

I have the following code:

 

class paypal_class {

private $ipn_status;                // holds the last status
public $admin_mail; 	// receive the ipn status report pre transaction
public $paypal_mail;	// paypal account, if set, class need to verify receiver
public $txn_id;		// array: if the txn_id array existed, class need to verified the txn_id duplicate
public $ipn_log;                    // bool: log IPN results to text file?
private $ipn_response;              // holds the IPN response from paypal   
public $ipn_data = array();         // array contains the POST values for IPN
private $fields = array();          // array holds the fields to submit to paypal
private $ipn_debug; 				// ipn_debug

// initialization constructor.  Called when class is created.
function __construct() { 
etc...

 

Howerver, I'm getting the error Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' on Line 3

 

Any ideas as to why this may be? It's a Paypal IPN script that I downloaded and looking at the responses it received seemed to work fine for everyone else.

 

Thanks for your help.

Your problem may be that you're running on PHP 4 which does not support the visibility keywords public/private/protected. To see what version of PHP you're running create a new file and place this inside:

 

<?php
phpinfo();
?>

I had a feeling it may have been something to do with the version I'm using.

 

And yes, it's version 4.

 

Is there a workaround for this within version 4?

The PHP 4 way to define class properties is to use the var keyword. So something like this:

 

class paypal_class {

var $ipn_status;                // holds the last status
var $admin_mail; 	// receive the ipn status report pre transaction
var $paypal_mail;
...

 

But because this class was apparently developed for PHP 5 there's a good chance you'll run into other compatibility issues as well.

The end of life and end of support for php4 was over two and a half years ago. Your web host should have provided a way of upgrading to php5, either through your web hosting control panel or through a setting in a .htaccess file...
