Error on my PDO Construct - Php - php

Question

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

#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);

Answer 1

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.

Answer 2

Can u try
$dbconn = new PDO('mysql:host=localhost;port=3306;dbname=thedb');
$q = $dbconn->prepare("SELECT thecol FROM thetbl", array(PDO::ATTR_PERSISTENT => true));
