想学习php.html" target="_blank">php的过程中你是否有尝试过将PHP把网页保存为word文件呢?但是也有很多小伙伴们不知道如何将PHP把网页保存为word文件,那么我们现在就一起去看看吧,想了解的小伙伴们赶紧收藏起来哦。
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
使用官方实例:
?
// 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
?
?* 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
$content = file_get_contents($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
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:
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);
??? }
}

';
//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
