PHP生成word文档的三种实现方式

这个函数的主要功能其实就是分析HTML代码中的所有图片地址，并且依次下载下来。获取到了图片的内容以后，调用MhtFileMaker类，将图片添加到mht文件中。具体的添加细节，封装在MhtFileMaker类中了。

使用方法：远程调用

url= http://www.***.com;
 
$content = file_get_contents($url);
 
$fileContent = getWordDocument($content,"//www.jb51.net/Music/etc/");
$fp = fopen("test.doc", 'w');
fwrite($fp, $fileContent);
fclose($fp);

其中，$content变量应该是HTML源代码，后面的链接应该是能填补HTML代码中图片相对路径的URL地址

本地生成调用：

header("Cache-Control: no-cache, must-revalidate"); 
header("Pragma: no-cache"); 
$wordStr = '//www.jb51.net/'; 
$fileContent = getWordDocument($wordStr); 
$fileName = iconv("utf-8", "GBK", ‘jb51' . '_'. $intro . '_' . rand(100, 999)); 
header("Content-Type: application/doc"); 
header("Content-Disposition: attachment; filename=" . $fileName . ".doc"); 
echo $fileContent;

注意，在使用这个函数之前，您需要先包含类MhtFileMaker，这个类可以帮助我们生成Mht文档。
