我把phpExcel包直接放在extend目录下，然后
\think\Loader::import('PHPExcel.PHPExcel.IOFactory');
$objReader = \PHPExcel\PHPExcel_IOFactory::createReader('Excel5');报错Class 'PHPExcel\PHPExcel_IOFactory' not found改成\think\Loader::import('PHPExcel.PHPExcel.IOFactory');
$objReader = PHPExcel_IOFactory::createReader('Excel5'); 报Class 'app\admin\controller\PHPExcel_IOFactory' not found请问这里要怎么调用！ 最佳答案
