  之前我的PHP教程博客访友询问使用php excel reader2.21导出excel时中文出现乱码如何解决,现我说明下php excel reader导出excel中文乱码的解决方法,希望对使用php excel reader导出excel的朋友有所帮助。

  php excel reader介绍

  php excel reader是一个读取Excel xsl文件内容的一个php excel类,目前最新版本是php excel reader2.21,网上可自行搜索,sourceforge上的php excel reader下载地址我估计是初始版,本教程所介绍的php excel reader导出excel中文乱码解决方法是基于php excel reader2.21,故不同版本php导出excel乱码的解决方法是有区别的,请务必下载正确的php excel reader版本。

  如何解决php excel reader2.21导出excel中文乱码?

  在下载完php excel reader2.21后,请解压至你的PHP环境配置的运行目录下,打开example.php,首先来看

1

$data = new Spreadsheet_Excel_Reader("example.xls");

  此语句是用来创建一个php导出excel的实例,在excel_reader2.php文件中我们可以找到此php excel reader类的构造函数原型

1

Spreadsheet_Excel_Reader($file='',$store_extended_info=true,$outputEncoding='')

  顾名思义,php excel reader导出excel文件内容的编码类型是通过$outputEncoding参数来指定的,默认的php excel reader导出excel的编码类型是通过变量_defaultEncoding设定,默认为UTF-8,所以通常解决php excel reader导出excel中文乱码有两种方法。

  php excel reader导出excel中文乱码解决方法一

1

$data = new Spreadsheet_Excel_Reader("example.xls");

改为

1

$data = new Spreadsheet_Excel_Reader("example.xls",true,"GB2312");

  php excel reader导出excel中文乱码解决方法二:打开excel_reader2.php,找到

1

var $_defaultEncoding = "UTF-8";

修改为

1

var $_defaultEncoding = "GB2312";

  即可解决php excel reader导出excel乱码的问题。

  那为什么通过上述教程修改后,如果在example.xls中添加中文后example.php仍然输出乱码呢?这是因为其调用了php excel reader类中的dump函数,此函数是用来将导出的excel文件内容以HTML的形式输出,而问题恰恰是由于这个函数中htmlentities函数作怪,htmlentities函数是用来把字符转换为HTML实体的,原型如下

1

htmlentities(string,quotestyle,character-set)

  其默认的字符集为ISO-8859-1,所以当使用php excel reader的dump函数导出excel出现中文乱码时,

  解决方法一

1

$val = htmlentities($val);

修改为

1

$val = htmlentities($val,ENT_COMPAT,"GB2312");

  解决方法二

1

$val = htmlentities($val);

修改为

1

$val = htmlspecialchars($val);

  php excel reader导出excel中文乱码解决方法总结

  如果不使用dump函数导出excel,可以通过修改_defaultEncoding变量或者通过new Spreadsheet_Excel_Reader(excel文件名,true,”GB2312″);解决导出excel乱码问题,如果使用dump函数以HTML的方式导出excel,需要修改htmlentities函数解决导出excel乱码问题。

  至此,使用php excel reader2.21导出excel中文乱码时如何解决就介绍完了。
