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。

PHP生成word原理

1.利用windows下面的 com组件

2.利用PHP将内容写入doc文件之中

具体实现：

1.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。

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}\n";
  
//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;
?>
Copy after login

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

1.生成mht格式（和HTML很相似）写入word

2.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(&#39;/<a\s*.*?\s*>(\s*.*?\s*)<\/a>/i&#39; , &#39;$1&#39; , $content); //去掉链接
  
 $images = array();
 $files = array();
 $matches = array();
 //这个算法要求src后的属性值必须使用引号括起来
 if ( preg_match_all(&#39;/<img[.\n]*?src\s*?=\s*?[\"\&#39;](.*?)[\"\&#39;](.*?)\/>/i&#39;,$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) == &#39;http://&#39;)
    {
     //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 , &#39;r&#39;) )
  {
   $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();
}
Copy after login

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/");
$fp = fopen("test.doc", &#39;w&#39;);
fwrite($fp, $fileContent);
fclose($fp);
Copy after login

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 = &#39;http://www.jb51.net/&#39;; 
$fileContent = getWordDocument($wordStr); 
$fileName = iconv("utf-8", "GBK", ‘jb51&#39; . &#39;_&#39;. $intro . &#39;_&#39; . rand(100, 999)); 
header("Content-Type: application/doc"); 
header("Content-Disposition: attachment; filename=" . $fileName . ".doc"); 
echo $fileContent;
Copy after login

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：

<?php
class word
{ 
function start()
{
ob_start();
echo &#39;<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">&#39;;
}
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);
}
}
Copy after login
$html = &#39; 
<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> 
&#39;; 
  
//批量生成 
for($i=1;$i<=3;$i++){ 
 $word = new word(); 
 $word->start(); 
 //$html = "aaa".$i; 
 $wordname = &#39;PHP淮北的个人网站--PHP10086.com&#39;.$i.".doc"; 
 echo $html; 
 $word->save($wordname); 
 ob_flush();//每次执行前刷新缓存 
 flush(); 
}
Copy after login

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

以上就是本文的全部内容，希望对大家的学习有所帮助。
