Thinkphp使用PHPExcel实现导入Excel

<?php
	class ExcelToArrary{  
		public function __construct(){  
			Vendor("Excel.PHPExcel");//引入phpexcel类(注意你自己的路径)  
			Vendor("Excel.PHPExcel.IOFactory");       
		}
		
		public function read($filename,$encode,$file_type){
			//判断excel表类型为2003还是2007 
            if(strtolower($file_type )=='xls'){  
				Vendor("Excel.PHPExcel.Reader.Excel5");   
                $objReader = PHPExcel_IOFactory::createReader('Excel5');  
			}elseif(strtolower($file_type )=='xlsx'){  
                Vendor("Excel.PHPExcel.Reader.Excel2007");   
                $objReader = PHPExcel_IOFactory::createReader('Excel2007');  
            } 
			
            $objReader->setReadDataOnly(true);			
            $objPHPExcel = $objReader->load($filename);
			
			//获取工作表的数目
			$sheetCount =$objPHPExcel->getSheetCount();
			$excelData = array();
			
			//循环工作表
			for($_s=0;$_s<$sheetCount;$_s++){
				//选择工作表
				$objWorksheet = $objPHPExcel->getSheet($_s);
				
				//取得一共有多少行
				$highestRow = $objWorksheet->getHighestRow();
				
				//取得一共有多少列
				$highestColumn = $objWorksheet->getHighestColumn();
				
				$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
				
				//循环组成三维数组  
				for ($row = 1;$row <= $highestRow;$row++){  
					for ($col = 0;$col < $highestColumnIndex;$col++){  
						$excelData[$_s][$row][]=(string)$objWorksheet->getCellByColumnAndRow($col, $row)->getValue();  
					}  
				}
			}
			
            return $excelData;
		}
