Detailed introduction to the sample code of three ways to generate word in PHP

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;
?>

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

  1. 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();
}


使用方法：远程调用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。

url= http://www.***.com;
 
$content =file_get_contents($url);
 
$fileContent = getWordDocument($content,"http://www.yoursite.com/Music/etc/");
$fp =fopen("test.doc",&#39;w&#39;);
fwrite($fp,$fileContent);
fclose($fp);


本地生成调用：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

header("Cache-Control: no-cache, must-revalidate"); 
header("Pragma: no-cache"); 
$wordStr = &#39;PHP淮北的个人网站--PHP10086.com&#39;; 
$fileContent = getWordDocument($wordStr); 
$fileName = iconv("utf-8", "GBK", ‘PHP淮北’ . &#39;_&#39;. $intro . &#39;_&#39; . 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。

2.纯HTML格式写入word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）

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);
}
}
$html = &#39;
<table width=600 cellpadding="6" cellspacing="1" bgcolor="#336699">

  </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();
}
