Class is giving me an Error

[treeleaf20]

All,

I'm getting the following error when I work with a class:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /webspace/httpdocs/offers/form_key.php on line 5

 

The complete code for this is class is:

<?php
class Form_Key
{

    protected $oldKey;

    public function __construct()
    {
        // Ensure we have an available session
        if ( NULL == session_id() )
        {
            session_start();
        }
        // Grab our former key for validation
        if ( isset( $_SESSION['form_key'] ) )
        {
            $this->oldKey = $_SESSION['form_key'];
        }
        // Assign the new key
        $_SESSION['form_key'] = md5( uniqid( mt_rand(), TRUE ) );
    }

    public function isValid()
    {
        return 'POST' == $_SERVER['REQUEST_METHOD']
            && isset( $_POST['form_key'] )
            && '' != trim( $_POST['form_key'] )
            && '' != trim( $this->oldKey )
            && $_POST['form_key'] === $this->oldKey;
    }

    public function getKey()
    {
        return $_SESSION['form_key'];
    }

    public function getOldKey()
    {
        return $this->oldKey;
    }

    public function render()
    {
        return '<input type="hidden" name="form_key" value="' . $_SESSION['form_key'] . '" />';
    }

    public function __toString()
    {
        return $this->render();
    }

} 
?>

 

The line that is giving the issue is this line:

protected $oldKey;

 

Is it ok just to remove this line?? If I comment it out it gives me the same message but for line 7, which is this one:

public function __construct()

 

Anyone have any ideas? Thanks in advance.

You must be running PHP4.

 

take away the protected/private parts.

In other words..

protected $oldKey

becomes

var $oldKey

 

or simply...

$oldKey = null;

[treeleaf20]

If I make it:

$oldKey = null;

I get the following error:

Parse error: syntax error, unexpected T_VARIABLE, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /usr/local/pem/vhosts/243668/webspace/httpdocs/offers/form_key.php on line 5

 

If I make it:

var $oldKey;

I get the following error:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /usr/local/pem/vhosts/243668/webspace/httpdocs/offers/form_key.php on line 7

 

Thanks.

Well apparently var $oldkey works then

 

Line 7 is bad because it begins with public.  Take out the public part and it'll go to line... something higher than 7

which would be the other "public" function

 

Take note that in PHP4, public, private, protected and static didn't exist.

 

The quick and dirty solution is to take all the private/protected/public parts out.

The ultimate fix would be to upgrade to PHP5, in which OOP is implemented correctly.. or traditionally rather.

That did the trick, I'm using domain.com. How can I tell what version of PHP they are using?

 

Thanks!

take away the... private parts.
