最近工作遇到关于生成word的问题
现在总结一下生成word的三种方法。
btw:好像只要是标题带PHP的貌似点击量都不是很高(哥哥我标题还是带上PHP了),不知道为什么,估计博客园上net技术大牛比较多吧,如果把java,.net,php比作程序员的女友,那么java是Oracle门下的大家闺秀,.net微软旗下的名门望族,PHP则是草根门下的山村野姑,这让我等PHP草民闷骚男情何以堪情何以堪。。牢骚发完了,正式写吧
PHP生成word原理- 利用windows下面的 com组件
- 利用PHP将内容写入doc文件之中
具体实现:利用windows下面的 com组件原理:com作为PHP的一个扩展类,安装过office的服务器会自动调用word.application的com,可以自动生成文档,PHP官方文档手册:http://www.php.net/manual/en/class.com.php
使用官方实例:
<?php// starting word$word = new COM("word.application") or die("Unable to instantiate Word");echo "Loaded Word, version {$word->Version}
"; //bring it to front$word->Visible = 1; //open an empty document$word->Documents->Add(); //do some weird stuff$word->Selection->TypeText("This is a test...");$word->Documents[1]->SaveAs("Useless test.doc"); //closing word$word->Quit(); //free the object$word = null;?>
个人建议:com实例后的方法都需要查找官方文档才知道什么意思,编辑器没有代码提示,非常不方便,另外这个效率也不是很高,不推荐使用
利用PHP将内容写入doc文件之中这个方法又可以分为两种方法
- 生成mht格式(和HTML很相似)写入word
- 纯HTML格式写入word
生成mht格式(和HTML很相似)写入word/** * 根据HTML代码获取word文档内容 * 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 * 该函数依赖于类MhtFileMaker * 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 ** @param string $content HTML内容 * @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 * @param bool $isEraseLink 是否去掉HTML内容中的链接 */function getWordDocument( $content , $absolutePath = "" , $isEraseLink = true ){ $mht = new MhtFileMaker(); if ($isEraseLink)$content = preg_replace("/<as*.*?s*>(s*.*?s*)</a>/i" , "$1" , $content); //去掉链接$images = array(); $files = array(); $matches = array(); //这个算法要求src后的属性值必须使用引号括起来 if ( preg_match_all("/<img[.
]*?srcs*?=s*?[""](.*?)[""](.*?)/>/i",$content ,$matches ) ) {$arrPath = $matches[1];for ( $i=0;$i<count($arrPath);$i++){ $path = $arrPath[$i]; $imgPath = trim( $path ); if ( $imgPath != "" ) {$files[] = $imgPath;if( substr($imgPath,0,7) == "http://"){ //绝对链接,不加前缀}else{ $imgPath = $absolutePath.$imgPath;}$images[] = $imgPath; }} } $mht->AddContents("tmp.html",$mht->GetMimeType("tmp.html"),$content); for ( $i=0;$i<count($images);$i++) {$image = $images[$i];if ( @fopen($image , "r") ){ $imgcontent = @file_get_contents( $image ); if ( $content )$mht->AddContents($files[$i],$mht->GetMimeType($image),$imgcontent);}else{ echo "file:".$image." not exist!<br />";} } return $mht->GetFile();}
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,"http://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 = "http://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。

点评:这种方法的缺点是不支持批量生成下载,因为一个页面只能有一个header,(无论远程使用还是本地生成声明header页面只能输出一个header),即使你循环生成,结果还是只有一个word生成(当然你可以修改上面的方式来实现)
2.纯HTML格式写入word原理:
利用ob_start把html页面先存储起来(解决一下页面多个header问题,可以批量生成),然后在写入doc文档内容利用
代码:
<?phpclass word{ function start(){ob_start();echo "<html xmlns:o="urn:schemas-microsoft-com:office:office"xmlns:w="urn:schemas-microsoft-com:office:word"xmlns="http://www.w3.org/TR/REC-html40">";}function save($path){ echo "</html>";$data = ob_get_contents();ob_end_clean(); $this->wirtefile ($path,$data);} function wirtefile ($fn,$data){$fp=fopen($fn,"wb");fwrite($fp,$data);fclose($fp);}}
$html = " <table width=600 cellpadding="6" cellspacing="1" bgcolor="#336699"> <tr bgcolor="White"><td>PHP10086</td><td><a href="http://www.php10086.com" target="_blank" >http://www.php10086.com</a></td> </tr> <tr bgcolor="red"><td>PHP10086</td><td><a href="http://www.php10086.com" target="_blank" >http://www.php10086.com</a></td> </tr> <tr bgcolor="White"><td colspan=2 >PHP10086<br>最靠谱的PHP技术博客分享网站<img src="http://www.php10086.com/wp-content/themes/WPortal-Blue/images/logo.gif"></td> </tr> </table> ";//批量生成 for($i=1;$i<=3;$i++){$word = new word();$word->start();//$html = "aaa".$i;$wordname = "PHP淮北的个人网站--PHP10086.com".$i.".doc";echo $html;$word->save($wordname);ob_flush();//每次执行前刷新缓存flush(); }
个人点评:这种方法效果最好,原因有两个:
第一代码比较简洁,很容易理解,第二种支持批量生成word(这个很重要)
第三支持完整的html代码
生成了三个word文档:并且内容支持完整的html代码显示,第三种方法强烈推荐
