PHP把網(wǎng)頁(yè)保存為word文件的三種方法

更新時(shí)間：2014年04月01日 10:05:21 作者：

最近工作遇到關(guān)于生成word的問(wèn)題,現(xiàn)在總結(jié)一下生成word的三種方法的相關(guān)資料,需要的朋友可以參考下

一、PHP生成word的兩種思路或原理

1.利用windows下面的 com組件
2.利用PHP將內(nèi)容寫入doc文件之中
具體實(shí)現(xiàn)方法如下。

二、利用windows下面的com組件

原理：com作為PHP的一個(gè)擴(kuò)展類，安裝過(guò)office的服務(wù)器會(huì)自動(dòng)調(diào)用word.application的com，可以自動(dòng)生成文檔，PHP官方文檔手冊(cè)：http://www.php.net/manual/en/class.com.php

使用官方實(shí)例：

復(fù)制代碼代碼如下:

<?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;
?>

個(gè)人建議：com實(shí)例后的方法都需要查找官方文檔才知道什么意思，編輯器沒(méi)有代碼提示，非常不方便，另外這個(gè)效率也不是很高，不推薦使用

三、利用PHP將內(nèi)容寫入doc文件之中
這個(gè)方法又可以分為兩種方法

1.生成mht格式（和HTML很相似）寫入word
2.純HTML格式寫入word

1）、生成mht格式（和HTML很相似）寫入word

復(fù)制代碼代碼如下:

/**
 * 根據(jù)HTML代碼獲取word文檔內(nèi)容
 * 創(chuàng)建一個(gè)本質(zhì)為mht的文檔，該函數(shù)會(huì)分析文件內(nèi)容并從遠(yuǎn)程下載頁(yè)面中的圖片資源
 * 該函數(shù)依賴于類MhtFileMaker
 * 該函數(shù)會(huì)分析img標(biāo)簽，提取src的屬性值。但是，src的屬性值必須被引號(hào)包圍，否則不能提取
 * 
 * @param string $content HTML內(nèi)容
 * @param string $absolutePath 網(wǎng)頁(yè)的絕對(duì)路徑。如果HTML內(nèi)容里的圖片路徑為相對(duì)路徑，那么就需要填寫這個(gè)參數(shù)，來(lái)讓該函數(shù)自動(dòng)填補(bǔ)成絕對(duì)路徑。這個(gè)參數(shù)最后需要以/結(jié)束
 * @param bool $isEraseLink 是否去掉HTML內(nèi)容中的鏈接
 */
function getWordDocument( $content , $absolutePath = "" , $isEraseLink = true )
{
    $mht = new MhtFileMaker();
    if ($isEraseLink)
        $content = preg_replace('/<a\s*.*?\s*>(\s*.*?\s*)<\/a>/i' , '$1' , $content);   //去掉鏈接

    $images = array();
    $files = array();
    $matches = array();
    //這個(gè)算法要求src后的屬性值必須使用引號(hào)括起來(lái)
    if ( preg_match_all('/<img[.\n]*?src\s*?=\s*?[\"\'](.*?)[\"\'](.*?)\/>/i',$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://')
                {
                    //絕對(duì)鏈接，不加前綴
                }
                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();
}

這個(gè)函數(shù)的主要功能其實(shí)就是分析HTML代碼中的所有圖片地址，并且依次下載下來(lái)。獲取到了圖片的內(nèi)容以后，調(diào)用MhtFileMaker類，將圖片添加到mht文件中。具體的添加細(xì)節(jié)，封裝在MhtFileMaker類中了。

使用方法1：遠(yuǎn)程調(diào)用

復(fù)制代碼代碼如下:

$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變量應(yīng)該是HTML源代碼，后面的鏈接應(yīng)該是能填補(bǔ)HTML代碼中圖片相對(duì)路徑的URL地址

其中，$content變量應(yīng)該是HTML源代碼，后面的鏈接應(yīng)該是能填補(bǔ)HTML代碼中圖片相對(duì)路徑的URL地址

使用方法2:本地生成調(diào)用

復(fù)制代碼代碼如下:

header("Cache-Control: no-cache, must-revalidate"); 
header("Pragma: no-cache"); 
$wordStr = 'PHP教程網(wǎng)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，在使用這個(gè)函數(shù)之前，您需要先包含類MhtFileMaker，這個(gè)類可以幫助我們生成Mht文檔。

復(fù)制代碼代碼如下:

點(diǎn)評(píng)：這種方法的缺點(diǎn)是不支持批量生成下載，因?yàn)橐粋€(gè)頁(yè)面只能有一個(gè)header，（無(wú)論遠(yuǎn)程使用還是本地生成聲明header頁(yè)面只能輸出一個(gè)header），即使你循環(huán)生成，結(jié)果還是只有一個(gè)word生成（當(dāng)然你可以修改上面的方式來(lái)實(shí)現(xiàn)）

2.純HTML格式寫入word

原理：

利用ob_start把html頁(yè)面先存儲(chǔ)起來(lái)（解決一下頁(yè)面多個(gè)header問(wèn)題，可以批量生成），然后在寫入doc文檔內(nèi)容利用

代碼：

復(fù)制代碼代碼如下:

<?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);
    }
}

復(fù)制代碼代碼如下:

$html = '

//批量生成 
for($i=1;$i<=3;$i++){ 
    $word = new word(); 
    $word->start(); 
    //$html = "aaa".$i; 
    $wordname = 'PHP教程網(wǎng)站--jb51.net'.$i.".doc"; 
    echo $html; 
    $word->save($wordname); 
    ob_flush();//每次執(zhí)行前刷新緩存 
    flush();
