'class'=>'application.extensions.PHPExcel',
),
modify /protected/extensions/PHPExcel/Autoloader.php
public static function Register() {
$functions = spl_autoload_functions();
foreach($functions as $function)
spl_autoload_unregister($function);
$functions=array_merge(array(array('PHPExcel_Autoloader', 'Load')), $functions);
foreach($functions as $function)

}// function Register()
Then, trying create PHPExcel object $objPHPExcel = new PHPExcel();
but have an error: include(PHPExcel.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory in Z:\home\yii.local\www\framework\YiiBase.php(418)

Answer 1

try these, it work for me.
Copy files. Copy all files of PHPExcel in ROOT\protected\vendors\PHPExcel. This folder PHPExcel is the folder Classes renamed. Like these:
ROOT\protected\vendors\PHPExcel\
PHPExcel.php
PHPExcel\...
all files php
Load the clases PHPExcel. Modify the file ROOT\index.php. You will change how run the yii app.
$app = Yii::createWebApplication($config);
// adding PHPExcel autoloader
Yii::import('application.vendors.*');
require_once "PHPExcel/PHPExcel.php";
require_once "PHPExcel/PHPExcel/Autoloader.php";
Yii::registerAutoloader(array('PHPExcel_Autoloader','Load'), true);
$app->run();
Test your PHPExcel. Create a action in any controller
public function actionExcel(){
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A1', 'Hello')
->setCellValue('B2', 'world!')
->setCellValue('C1', 'Hello')
->setCellValue('D2', 'world!');
$objPHPExcel->getActiveSheet()->setTitle('Simple');
$objPHPExcel->setActiveSheetIndex(0);
ob_end_clean();
ob_start();
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="test.xls"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
}

Seeing your other question, I guess you have found the answer. Alas ... you have to use the import in the config, not components. Something like this:
// autoloading model and component classes
'import'=>array(
'application.models.*',
'application.components.*',
'application.vendors.phpexcel.classes.*',
),
You should also put phpexcel in a folder called vendors, not extensions. It is third party software and does not extend Yii.
There is also a guide here that works with disabling Yii autoload, instead of disabling PHPExcel autoload.

Try this:
spl_autoload_unregister(array('YiiBase','autoload'));
Yii::import('ext.phpexcel.Classes.PHPExcel', true);
$objPHPExcel = new PHPExcel();
$activeSheet = $objPHPExcel->getActiveSheet();
spl_autoload_register(array('YiiBase','autoload'));
