將網頁匯出為Word文檔的php代碼介紹

/** * 根據html代碼擷取word文檔內容 * 建立一個本質為mht的文檔，該函數會分析檔案內容並從遠程下載頁面中的圖片資源 * 該函數依賴於類MhtFileMaker * 該函數會分析img標籤，提取src的屬性值。但是，src的屬性值必須被引號包圍，否則不能提取 * * @param string $content HTML內容 * @param string $absolutePath 網頁的絕對路徑。如果HTML內容裡的圖片路徑為相對路徑，那麼就需要填寫這個參數，來讓該函數自動填補成絕對路徑。這個參數最後需要以/結束 * @param bool $isEraseLink 是否去掉HTML內容中的連結 */ function getWordDocument( $content , $absolutePath = "" , $isEraseLink = true ) { $mht = new MhtFileMaker(); if ($isEraseLink) $content = preg_replace('/(\s*.*?\s*)<\/a>/i' , '$1' , $content); //去掉連結 $images = array(); $files = array(); $matches = array(); //這個演算法要求src後的屬性值必須使用引號括起來 if ( preg_match_all('//i',$content ,$matches ) ) { $arrPath = $matches[1]; for ( $i=0;$i{ $path = $arrPath[$i]; $imgPath = trim( $path ); if ( $imgPath != "" ) { $files[] = $imgPath; if( substr($imgPath,0,7) == 'http://') { //絕對連結，不加首碼 } else { $imgPath = $absolutePath.$imgPath; } $images[] = $imgPath; } } } $mht->AddContents("tmp.html",$mht->GetMimeType("tmp.html"),$content); for ( $i=0;$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! "; } } return $mht->GetFile(); } 複製代碼 使用方法： $fileContent = getWordDocument($content,"http://www.yoursite.com/Music/etc/"); $fp = fopen("test.doc", 'w'); fwrite($fp, $fileContent); fclose($fp); 複製代碼 其中，$content變數應該是HTML原始碼，後面的連結應該是能填補HTML代碼中圖片相對路徑的URL地址 注意，在使用這個函數之前，您需要先包含類MhtFileMaker，這個類可以協助我們產生Mht文檔。 /*********************************************************************** Class: Mht File Maker Version: 1.2 beta link: http://bbs.it-home.org Author: Wudi Description: The class can make .mht file. ***********************************************************************/ 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())) .
