[RESOLVED] Undefined Variable

[mar_zim]

Sorry to ask this n00b question.
It's just my 2nd day in php.

I have this class database connection:

<?php
class DBConnection{

private $link;

public function connect(){
include 'connstring.php';
$link = mysql_connect($host,$user,$pw);
if(!$link)
{
    die('Could not connect'.mysql_error());
}
}

public function close()
{
    mysql_close($link);
}
}
?>

But when I call connect and close function the errors come out.

Notice: Undefined variable: link in C:\Program Files\Apache Group\Apache2\htdocs\connection.php on line 16

Warning: mysql_close(): supplied argument is not a valid MySQL-Link resource in C:\Program Files\Apache Group\Apache2\htdocs\connection.php on line 16

why?

edit: using

$this->link 

do the trick.

Have you seen the article in my sig about PHP 5 OOP? I have made a database wrapper example there. You may find it useful, even if your script isn't in PHP 5.
