yii phpexcel <转>

原文详情参见 这里

1、下载phpexcel，将压缩包中的classes复制到protected/extensions下并修改为PHPExcel。

2、修改YII配置文件config/main.php

[php] view plaincopy





'import'=>array(

'application.extensions.PHPExcel.PHPExcel',

),

（以下处理PHPExcel autoload和YII autoload相冲突的方法任选其一，推荐第4种，最符合YII标准）
3.1、修改PHPExcel中的Autoloader.php

[php] view plaincopy





PHPExcel_Autoloader::Register();

PHPExcel_Shared_ZipStreamWrapper::register();

修改为

[php] view plaincopy





Yii::registerAutoloader(array('PHPExcel_Autoloader','Register'),true);

3.2、按照下面的代码修改PHPExcel代码目录里的Autoloader.php文件

[php] view plaincopy





public static function Register() {

/*

if (function_exists('__autoload')) {

//Register any existing autoloader function with SPL, so we don't get any clashes

spl_autoload_register('__autoload');

}

//Register ourselves with SPL

return spl_autoload_register(array('PHPExcel_Autoloader', 'Load'));

*/

$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)

$x = spl_autoload_register($function);

return $x;

} // function Register()

3.3、在需要使用PHPExcel时使用以下代码

[php] view plaincopy





$filePath = '/home/public_html/sqt/protected/data/queueSql/company.xls';

spl_autoload_unregister(array('YiiBase', 'autoload'));

$phpExcelPath = Yii::getPathOfAlias('application.extensions.PHPExcel.PHPExcel');

include($phpExcelPath . DIRECTORY_SEPARATOR . 'IOFactory.php');

spl_autoload_register(array('YiiBase', 'autoload'));

$PHPExcel = PHPExcel_IOFactory::load( $filePath);

3.4、只要设置Yii::$enableIncludePath为false，第三方类库就有了执行自己的autoload方法的机会，并且不需要配置config/main.php，非常方便灵活

[php] view plaincopy





Yii::$enableIncludePath = false;

Yii::import('application.extensions.PHPExcel.PHPExcel', 1);

-------------------------------------------------------------------------------
导入Excel文件方法

[php] view plaincopy





public function actionLoad() {

if(isset($_POST['submit'])) {

$file = CUploadedFile::getInstanceByName('file');//获取上传的文件实例

if($file->getType() == 'application/vnd.ms-excel') {

$excelFile = $file->getTempName();//获取文件名

//这里就是导入PHPExcel包了，要用的时候就加这么两句，方便吧

Yii::$enableIncludePath = false;

Yii::import('application.extensions.PHPExcel.PHPExcel', 1);

$phpexcel = new PHPExcel;

$excelReader = PHPExcel_IOFactory::createReader('Excel5');

$phpexcel = $excelReader->load($excelFile)->getSheet(0);//载入文件并获取第一个sheet

$total_line = $phpexcel->getHighestRow();

$total_column = $phpexcel->getHighestColumn();

for ($row = 2; $row <= $total_line; $row++) {

$data = array();

for ($column = 'A'; $column <= $total_column; $column++) {

$data[] = trim($phpexcel->getCell($column.$row) -> getValue());

}

}

}

}

}
