PHP把网页保存为word文件的三种方法

一、php生成word的两种思路或原理

1.利用windows下面的 com组件
2.利用php将内容写入doc文件之中
具体实现方法如下。

二、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:

复制代码 代码如下:<?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

三、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


1)、生成mht格式(和HTML很相似)写入word

复制代码 代码如下:/**
 * 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('/<a/s*.*?/s*>(/s*.*?/s*)<//a>/i' , '$1' , $content);   //去掉链接

    $images = array();
    $files = array();
    $matches = array();
    //这个算法要求src后的属性值必须使用引号括起来
    if ( preg_match_all('/<img[./n]*?src/s*?=/s*?[/"/'](.*?)[/"/'](.*?)//>/i',$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1:远程调用
复制代码 代码如下:$url= http://www.***.com;

$content = file_get_contents($url);

$fileContent = getWordDocument($content,"http://www.yoursite.com/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


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

使用方法2:本地生成调用
复制代码 代码如下:
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
$wordStr = 'php教程网站--jb51.NET';
$fileContent = getWordDocument($wordStr);
$fileName = iconv("utf-8", "GBK", ‘php教程' . '_'. $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:
复制代码 代码如下:<?php
class 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($fp);
    }
}
复制代码 代码如下:$html = '
<table width=600 cellpadding="6" cellspacing="1" bgcolor="#336699">
<tr bgcolor="White">
  <td>php10086</td>
  <td><a href="http://www.jb51.NET" target="_blank" >http://www.jb51.NET</a></td>
</tr>
<tr bgcolor="red">
  <td>php10086</td>
  <td><a href="http://www.jb51.NET" target="_blank" >http://www.jb51.NET</a></td>
</tr>
<tr bgcolor="White">
  <td colspan=2 >
  php10086<br>
  最靠谱的php技术分享网站
  <img src="http://www.jb51.NET/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;
    $wordname = 'php教程网站--jb51.NET'.$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,原因有三个:

第一代码比较简洁,很容易理解
第二是支持批量生成word(这个很重要)
第三是支持完整的html代码
