Hey,

Is there any difference between $this->link and $this->_link ?
(link being a pdo connection)

Also, is there a difference between

$this->link->prepare()
And:

$this->_link->prepare()

[JackOfAllTrades]

link and _link are two different variables, aren't they?

<?php

class Link
{
    public function __construct($link, $_link)
    {
        $this->link = $link;
        $this->_link = $_link;
    }

    public function printLinks()
    {
        echo "{$this->link} {$this->_link}\n";
    }
    private $link;
    private $_link;
}

$l = new Link("link1", "link2");
$l->printLinks();

php -f link.php 
link1 link2

Ah, you've cleared that up for me, was wondering why there was no documentation on it :|

I honestly don't know why I've used $this->_link half the occurrences and $this->link for the rest :S
