Issue import vendor file in cakephp

I'm trying to import a non cake php file into a view. I copied the file into the Vendors folder and then added the following line to my code:

<?php
App::import('Vendor', 'sitecommon');
?>

But this gives me the following error message:

Fatal error: Cannot redeclare class IncFunc in /var/www/html/PHP/site/includes/sitecommon.php on line 6

But if I remove the import statement I get the message:

Class 'IncFunc' not found in <b>/var/www/html/cakepftest/app/views/alerts/view.ctp

This is for cake version 1.3.7.

<?php


//various include functions for javascript libraries,etc.
class IncFunc
{

This means you're declaring the class IncFunc twice, like:

class IncFunc {
   ...
}

// somewhere else
class IncFunc {
   ...
}

Remove one of the declarations.

Doesn't really solve the problem of why it's happening, but you could:

<?php

if (!class_exists('IncFunc')) {
    App::import('Vendor', 'sitecommon');
}

?>
