"Constant CRLF already defined" error when using php-resque with Laravel - php

Question

I'm running php-resque together with Laravel 3 on Ubuntu 12.04.
Problem: When a job is enqueued in resque, I get the following error:
Unhandled Exception
Message:
Constant CRLF already defined
Location:
/var/www/dev/vendor/chrisboulton/php-resque/lib/Redisent/Redisent.php on line 10
What does the error mean and how can we solve it?
PHP
// Enqueue in Resque
$data = array(
'name' => $name,
'email' => $email,
'created_at' => DB::raw('NOW()')
);
Resque::enqueue('queue', 'exampleWorker', $data);
However when I try to enqueue a job using artisan, it works!
Task
class Queue_Task
{
public function run()
{
// Autoload composer vendors.
require path('composer').DS.'autoload.php';
$args = array('name' => 'John Smith');
Resque::enqueue('MyAppName', 'ExampleWorker', $args);
echo "Resque job queued.\n";
return;
}
}
Output
PHP Notice: Constant CRLF already defined in /var/www/dev/vendor/chrisboulton/php-resque/lib/Redisent/Redisent.php on line 10

Resque job queued.

Answer 1

It's a guess, but I'd say in /var/www/dev/vendor/chrisboulton/php-resque/lib/Redisent/Redisent.php there's a second define('CRLF', 'something') on line 10 that should probably be commented out if you want these two pieces of software to work together.
