Call to undefined function query() - using PDO in PHP
- by webworm
I have a written a script in PHP that reads from data from a MySQL database. I am new to PHP and I have been using the PDO library. I have been developing on a Windows machine using the WAMP Server 2 and all has been working well. However, when I uploaded my script to the LINUX server where it will be used I get the following error when I run my script.
Fatal error: Call to undefined function query()
This is the line where the error is occuring ...
foreach($dbconn->query($sql) as $row)
The variable $dbconn is first defined in my dblogin.php include file which I am listing below.
<?php
// Login info for the database
$db_hostname = 'localhost';
$db_database = 'MY_DATABASE_NAME';
$db_username = 'MY_DATABASE_USER';
$db_password = 'MY_DATABASE_PASSWORD';
$dsn = 'mysql:host=' . $db_hostname . ';dbname=' . $db_database . ';';
try
{
$dbconn = new PDO($dsn, $db_username, $db_password);
$dbconn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch (PDOException $e)
{
echo 'Error connecting to database: ' . $e->getMessage();
}
?>
Inside the function where the error occurs I have the database connection defined as a superglobal as such ...
global $dbconn;
I am a bit confused as to what is happening since all worked well on my development machine. I was wondering if the PDO library was installed but from what I thought it was installed by default as part of PHP v5.
The script is running on an Ubuntu (5.0.51a-3ubuntu5.4) machine and the PHP version is 5.2.4. Thank you for any suggestions. I am really lost on this.
