PHP生成word原理php

利用windows下面的 com組件
利用PHP將內容寫入doc文件之中

具體實現：css

利用windows下面的 com組件html

原理：com做爲PHP的一個擴展類，安裝過office的服務器會自動調用word.application的com，能夠自動生成文檔，PHP官方文檔手冊：http://www.php.net/manual/en/class.com.php算法

使用官方實例：windows

<?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;

我的建議：com實例後的方法都須要查找官方文檔才知道什麼意思，編輯器沒有代碼提示，很是不方便，另外這個效率也不是很高，不推薦使用緩存

利用PHP將內容寫入doc文件之中服務器

這個方法又能夠分爲兩種方法app

生成mht格式（和HTML很類似）寫入word
純HTML格式寫入word

生成mht格式（和HTML很類似）寫入wordless

這個函數的主要功能其實就是分析HTML代碼中的全部圖片地址，而且依次下載下來。獲取到了圖片的內容之後，調用MhtFileMaker類，將圖片添加到mht文件中。具體的添加細節，封裝在MhtFileMaker類中了。編輯器

使用方法：遠程調用

其中，$content變量應該是HTML源代碼，後面的連接應該是能填補HTML代碼中圖片相對路徑的URL地址

本地生成調用：

header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
$wordStr = 'http://www.jb51.net/';
$fileContent = getWordDocument($wordStr);
$fileName = iconv("utf-8", "GBK", ‘jb51' . '_'. $intro . '_' . rand(100, 999)); 
header("Content-Type: application/doc");
header("Content-Disposition: attachment; filename=" . $fileName . ".doc");
echo $fileContent;

注意，在使用這個函數以前，您須要先包含類MhtFileMaker，這個類能夠幫助咱們生成Mht文檔。

<?php
  
class MhtFileMaker{
 var $config = array();
 var $headers = array();
 var $headers_exists = array();
 var $files = array();
 var $boundary;
 var $dir_base;
 var $page_first;
  
 function MhtFile($config = array()){
  
 }
  
 function SetHeader($header){
  $this->headers[] = $header;
  $key = strtolower(substr($header, 0, strpos($header, ':')));
  $this->headers_exists[$key] = TRUE;
 }
  
 function SetFrom($from){
  $this->SetHeader("From: $from");
 }
  
 function SetSubject($subject){
  $this->SetHeader("Subject: $subject");
 }
  
 function SetDate($date = NULL, $istimestamp = FALSE){
  if ($date == NULL) {
   $date = time();
  }
  if ($istimestamp == TRUE) {
   $date = date('D, d M Y H:i:s O', $date);
  }
  $this->SetHeader("Date: $date");
 }
  
 function SetBoundary($boundary = NULL){
  if ($boundary == NULL) {
   $this->boundary = '--' . strtoupper(md5(mt_rand())) . '_MULTIPART_MIXED';
  } else {
   $this->boundary = $boundary;
  }
 }
  
 function SetBaseDir($dir){
  $this->dir_base = str_replace("\\", "/", realpath($dir));
 }
  
 function SetFirstPage($filename){
  $this->page_first = str_replace("\\", "/", realpath("{$this->dir_base}/$filename"));
 }
  
 function AutoAddFiles(){
  if (!isset($this->page_first)) {
   exit ('Not set the first page.');
  }
  $filepath = str_replace($this->dir_base, '', $this->page_first);
  $filepath = 'http://mhtfile' . $filepath;
  $this->AddFile($this->page_first, $filepath, NULL);
  $this->AddDir($this->dir_base);
 }
  
 function AddDir($dir){
  $handle_dir = opendir($dir);
  while ($filename = readdir($handle_dir)) {
   if (($filename!='.') && ($filename!='..') && ("$dir/$filename"!=$this->page_first)) {
    if (is_dir("$dir/$filename")) {
     $this->AddDir("$dir/$filename");
    } elseif (is_file("$dir/$filename")) {
     $filepath = str_replace($this->dir_base, '', "$dir/$filename");
     $filepath = 'http://mhtfile' . $filepath;
     $this->AddFile("$dir/$filename", $filepath, NULL);
    }
   }
  }
  closedir($handle_dir);
 }
  
 function AddFile($filename, $filepath = NULL, $encoding = NULL){
  if ($filepath == NULL) {
   $filepath = $filename;
  }
  $mimetype = $this->GetMimeType($filename);
  $filecont = file_get_contents($filename);
  $this->AddContents($filepath, $mimetype, $filecont, $encoding);
 }
  
 function AddContents($filepath, $mimetype, $filecont, $encoding = NULL){
  if ($encoding == NULL) {
   $filecont = chunk_split(base64_encode($filecont), 76);
   $encoding = 'base64';
  }
  $this->files[] = array('filepath' => $filepath,
        'mimetype' => $mimetype,
        'filecont' => $filecont,
        'encoding' => $encoding);
 }
  
 function CheckHeaders(){
  if (!array_key_exists('date', $this->headers_exists)) {
   $this->SetDate(NULL, TRUE);
  }
  if ($this->boundary == NULL) {
   $this->SetBoundary();
  }
 }
  
 function CheckFiles(){
  if (count($this->files) == 0) {
   return FALSE;
  } else {
   return TRUE;
  }
 }
  
 function GetFile(){
  $this->CheckHeaders();
  if (!$this->CheckFiles()) {
   exit ('No file was added.');
  }
  $contents = implode("\r\n", $this->headers);
  $contents .= "\r\n";
  $contents .= "MIME-Version: 1.0\r\n";
  $contents .= "Content-Type: multipart/related;\r\n";
  $contents .= "\tboundary=\"{$this->boundary}\";\r\n";
  $contents .= "\ttype=\"" . $this->files[0]['mimetype'] . "\"\r\n";
  $contents .= "X-MimeOLE: Produced By Mht File Maker v1.0 beta\r\n";
  $contents .= "\r\n";
  $contents .= "This is a multi-part message in MIME format.\r\n";
  $contents .= "\r\n";
  foreach ($this->files as $file) {
   $contents .= "--{$this->boundary}\r\n";
   $contents .= "Content-Type: $file[mimetype]\r\n";
   $contents .= "Content-Transfer-Encoding: $file[encoding]\r\n";
   $contents .= "Content-Location: $file[filepath]\r\n";
   $contents .= "\r\n";
   $contents .= $file['filecont'];
   $contents .= "\r\n";
  }
  $contents .= "--{$this->boundary}--\r\n";
  return $contents;
 }
  
 function MakeFile($filename){
  $contents = $this->GetFile();
  $fp = fopen($filename, 'w');
  fwrite($fp, $contents);
  fclose($fp);
 }
  
 function GetMimeType($filename){
  $pathinfo = pathinfo($filename);
  switch ($pathinfo['extension']) {
   case 'htm': $mimetype = 'text/html'; break;
   case 'html': $mimetype = 'text/html'; break;
   case 'txt': $mimetype = 'text/plain'; break;
   case 'cgi': $mimetype = 'text/plain'; break;
   case 'php': $mimetype = 'text/plain'; break;
   case 'css': $mimetype = 'text/css'; break;
   case 'jpg': $mimetype = 'image/jpeg'; break;
   case 'jpeg': $mimetype = 'image/jpeg'; break;
   case 'jpe': $mimetype = 'image/jpeg'; break;
   case 'gif': $mimetype = 'image/gif'; break;
   case 'png': $mimetype = 'image/png'; break;
   default: $mimetype = 'application/octet-stream'; break;
  }
  return $mimetype;
 }
}
?>

點評：這種方法的缺點是不支持批量生成下載，由於一個頁面只能有一個header，（不管遠程使用仍是本地生成聲明header頁面只能輸出一個header），即便你循環生成，結果仍是隻有一個word生成（固然你能夠修改上面的方式來實現）

2.純HTML格式寫入word

原理：

利用ob_start把html頁面先存儲起來（解決一下頁面多個header問題，能夠批量生成），而後在寫入doc文檔內容利用

代碼：

<?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);
}
}
?
$html = '

</table>
';
  
//批量生成
for($i=1;$i<=3;$i++){
 $word = new word();
 $word->start();
 //$html = "aaa".$i;
 $wordname = 'PHP淮北的我的網站--PHP10086.com'.$i.".doc";
 echo $html;
 $word->save($wordname);
 ob_flush();//每次執行前刷新緩存
 flush();
}
