php读取excel文档内容（转载）

入到数据库的需要，php-excel-reader可以很轻松的使用它读取excel文件,本文将详细介绍，需要了解的朋友可以参考下

php开发中肯定会遇到将excel文件内容导入到数据库的需要，php-excel-reader是一个读取excel的类，可以很轻松的使用它读取excel文件非常方便。

php-excel-reader下载地址： http://www.jb51.net/codes/67223.html

我下载的是php-excel-reader-2.21版本，使用的时候还遇到几个小问题，后面再细说，先奉上php实例：

我使用的excel如下图：

php代码如下：

复制代码 代码如下:

 1 <?php
 2 /*by www.phpddt.com*/
 3 header("Content-Type:text/html;charset=utf-8");
 4 require_once ‘excel_reader2.php‘;
 5 //创建对象
 6 $data = new Spreadsheet_Excel_Reader();
 7 //设置文本输出编码
 8 $data->setOutputEncoding(‘UTF-8‘);
 9 //读取Excel文件
10 $data->read("example.xls");
11 //$data->sheets[0][‘numRows‘]为Excel行数
12 for ($i = 1; $i <= $data->sheets[0][‘numRows‘]; $i++) {
13 //$data->sheets[0][‘numCols‘]为Excel列数
14 for ($j = 1; $j <= $data->sheets[0][‘numCols‘]; $j++) {
15 //显示每个单元格内容
16 echo $data->sheets[0][‘cells‘][$i][$j].‘ ‘;
17 }
18 echo ‘<br>‘;
19 }
20 ?>

读取结果截图如下：

再来说说这个类的小问题：

(1)出现Deprecated: Function split() is deprecated in 。。。错误

解决：将excel_reader2.php源码中split改为explode,详情点击php中explode与split的区别介绍

(2)出现Deprecated: Assigning the return value of new by reference is deprecated in错误

解决：将excel_reader2.php源码中$this->_ole =& new OLERead()中 &去掉，因为php5.3中废除了=& 符号直接用=引用

(3)乱码问题解决：

构造函数是function
Spreadsheet_Excel_Reader($file=‘‘,$store_extended_info=true,$outputEncoding=‘‘)，
它默认的编码是utf-8,如果不指定，可能会出现乱码问题，可通过$data->setOutputEncoding(‘GBK‘);指定，还有
如果你使用dump()函数，dump()函数将excel内容一html格式输出,使用htmlentities将字符转化为html的,它默认使用
ISO8559-1编码的，所以你要将
excel_reader2.php源码中 htmlentities($val)函数改为
htmlentities($val,ENT_COMPAT,"GB2312");才行。

最后来说说，php-excel-reader操作excel中的两个重要的方法：

1.dump(),它可以将excel内容以html格式输出：

echo $data->dump(true,true);

2.将excel数据存入数组中，使用$data->sheets，打印下如下：

复制代码 代码如下:

  1 Array
  2 (
  3 　　[0] => Array
  4 　　　　(
  5 　　　　　　maxrow] => 0

使用NOPI读取Word、Excel文档内容

使用NOPI读取Excel的例子很多,读取Word的例子不多. Excel的解析方式有多中,可以使用ODBC查询,把Excel作为一个数据集对待.也可以使用文档结构模型的方式进行解析,即解析Workbook(工作簿).Sheet.Row.Column. Word的解析比较复杂,因为Word的文档结构模型定义较为复杂.解析Word或者Excel,关键是理解Word.Excel的文档对象模型. Word.Excel文档对象模型的解析,可以通过COM接口调用,此类方式使用较广.(可以录制宏代码,然后替

PHP读取excel文档

PHP读取excel文档 项目需要读取Excel的内容,从百度搜索了下,主要有两个选择,第一个是PHPExcelReader,另外一个是PHPExcel. PHPExcelReader比较轻量级,仅支持Excel的读取,实际上就是一个Reader.但是可惜的是不能够支持Excel 2007的格式(.xlsx). PHPExcel比较强大,能够将内存中的数据输出成Excel文件,同时还能够对Excel做各种操作,下面主要介绍下如何使用PHPExcel进行Excel 2007格式(.xlsx)文件的
