基于php中使用excel的简单介绍_PHP
在工作中需要处理多语言的翻译问题,翻译都是写在excel表格里面。为了处理方便我就保留中文和英文两列。
这样需要将这些数据从excel中取出来,然乎保存在excel的数组中,通过使用循环数组将相应的数据放入到数据库中。
所以工作的第一步就是要将数据从excel中取出来。这里我使用到了一个开源php处理excel类:phpexcel. 该项目的详细信息 http://phpexcel.codeplex.com/ 。
我目前使用的是phpexcel1.7.3版本, 解压缩后里面有一个PHPExcel和PHPExcel.php文件。
我们主要使用那个PHP文件。见下图文件目录结构
这个版本据说是可以支持excel2007,但是我使用2007编辑的xlsx是无法获得该库的支持。于是乎我就将它转化为2003。感觉支持地很好。
下面介绍一下具体的使用:
复制代码 代码如下:
require_once('./phpexcel1.7.3/PHPExcel.php');
$php_excel_obj = new PHPExcel();
$php_reader = newPHPExcel_Reader_Excel2007();
if(!$php_reader->canRead($file_name)){
$php_reader= new PHPExcel_Reader_Excel5();
if(!$php_reader->canRead($file_name)){
echo'NO Excel!';
}
}
$php_excel_obj = $php_reader->load($file_name);
$current_sheet =$php_excel_obj->getSheet(0);
上面的主要功能是初始化相关的excel类,并装载excel第一个sheet
复制代码 代码如下:
$all_column =$current_sheet->getHighestColumn();
$all_row =$current_sheet->getHighestRow();
以上分别获得该表格的最大列值(字母表示如:‘G'),和最大的行数(数值表示)
下面将使用循环来讲excel里面的数据读到excel中:
复制代码 代码如下:
$all_arr = array();
$c_arr = array();
//字符对照表
for($r_i = 1; $r_i $c_arr= array();
for($c_i= 'A'; $c_i $adr= $c_i . $r_i;
$value= $current_sheet->getCell($adr)->getValue();
if($c_i== 'A' && empty($value) ) break;
if(is_object($value)) $value= $value->__toString();
$c_arr[$c_i]= $value;
}
$c_arr&& $all_arr[] = $c_arr;
}
下面简单地介绍一下phpexcel的写操作,这个操作经常用于将数据库中的数据导入到excel中,便于展示和做成更美观的效果。
复制代码 代码如下:
require_once('./phpexcel1.7.3/PHPExcel.php');
$excel_obj = new PHPExcel();
$objWriter = newPHPExcel_Writer_Excel5($excel_obj);
$excel_obj->setActiveSheetIndex(0);
$act_sheet_obj=$excel_obj->getActiveSheet();
$act_sheet_obj->setTitle('sheet');
$act_sheet_obj->setCellValue('A1', '字符串内容');
$act_sheet_obj->setCellValue('A2', 26);
$file_name = "output.xls";
$objWriter->save($file_name);
代码很简单, 首先初始化相关的excel写类,然后写入数据,最后保存为xls文件。
输出的效果见图
