将网页导出为Word文档的php代码介绍

2. /**
3. * 根据html代码获取word文档内容
4. * 创建一个本质为mht的文档，该函数会分析文件内容并从远程下载页面中的图片资源
5. * 该函数依赖于类MhtFileMaker
6. * 该函数会分析img标签，提取src的属性值。但是，src的属性值必须被引号包围，否则不能提取
7. *
8. * @param string $content HTML内容
9. * @param string $absolutePath 网页的绝对路径。如果HTML内容里的图片路径为相对路径，那么就需要填写这个参数，来让该函数自动填补成绝对路径。这个参数最后需要以/结束
10. * @param bool $isEraseLink 是否去掉HTML内容中的链接
11. */
12. function getWordDocument( $content , $absolutePath = "" , $isEraseLink = true )
13. {
14. $mht = new MhtFileMaker();
15. if ($isEraseLink)
16. $content = preg_replace('/(\s*.*?\s*)<\/a>/i' , '$1' , $content); //去掉链接
17. $images = array();
18. $files = array();
19. $matches = array();
20. //这个算法要求src后的属性值必须使用引号括起来
21. if ( preg_match_all('//i',$content ,$matches ) )
22. {
23. $arrPath = $matches[1];
24. for ( $i=0;$i{
25. $path = $arrPath[$i];
26. $imgPath = trim( $path );
27. if ( $imgPath != "" )
28. {
29. $files[] = $imgPath;
30. if( substr($imgPath,0,7) == 'http://')
31. {
32. //绝对链接，不加前缀
33. }
34. else
35. {
36. $imgPath = $absolutePath.$imgPath;
37. }
38. $images[] = $imgPath;
39. }
40. }
41. }
42. $mht->AddContents("tmp.html",$mht->GetMimeType("tmp.html"),$content);
43. for ( $i=0;$i{
44. $image = $images[$i];
45. if ( @fopen($image , 'r') )
46. {
47. $imgcontent = @file_get_contents( $image );
48. if ( $content )
49. $mht->AddContents($files[$i],$mht->GetMimeType($image),$imgcontent);
50. }
51. else
52. {
53. echo "file:".$image." not exist!
    ";
54. }
55. }
56. return $mht->GetFile();
57. }

使用方法：

2. $fileContent = getWordDocument($content,"http://www.yoursite.com/Music/etc/");
3. $fp = fopen("test.doc", 'w');
4. fwrite($fp, $fileContent);
5. fclose($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 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。
