Error on my PDO Construct - Php

It's whining of line 6: Warning: PDO::__construct() expects parameter 2 to be string, array given

Along with a line 7 error: 

Fatal error: Call to a member function prepare() on a non-object in

How do I fix this? I've tested the query and it works fine..

<?php

## Loop through results from mysql
try{
    #connection string
        $dbconn = new PDO('mysql:host=localhost;port=3306;dbname=thedb',array(PDO::ATTR_PERSISTENT => true));
        $q = $dbconn->prepare("SELECT thecol FROM thetbl");
    #call stored proc
        $q->execute();
    #get the rows into an array
        $result = $q->fetchAll();
        foreach($result as $r){
            $xmlUrl = $r['FW_ArtSrcLink'];
            $ConvertToXml = simplexml_load_file($xmlUrl);
            # -> Setup XML
            $newsStory = $ConvertToXml->channel->item;
        }   

    # -----> Load News Stories
        for($i = 0;$i<sizeof($newsStory); $i++){

    # Source of Article Info-->
            $SrcTitle=$newsStory[$i]->title;
            $SrcLink=$newsStory[$i]->link;

    # Actual News Article Info -->
            $title=$newsStory[$i]->title;
            $desc=$newsStory[$i]->description;

    # Output Results ------------>      
            echo '<hr>';
            echo '<strong>'.'Title:'.$title.'</strong>'.'(via: <a href=\''.$SrcLink.'\'>'.$SrcTitle.'</a>'.'<br />';

You're initializing the PDO object incorrectly, the second parameter of the constructor should be the username, not an array of options.

$dbconn = new PDO('mysql:host=localhost;port=3306;dbname=thedb',array(PDO::ATTR_PERSISTENT => true));

should be,

$dbconn = new PDO('mysql:host=localhost;port=3306;dbname=thedb',
                  'yourusername',
                  'yourpassword',
                  array(PDO::ATTR_PERSISTENT => true));

See the PHP manual page for PDO::__construct() for more information.

The second error you're getting because the $dbconn object wasn't created properly due to the first error.
