如何從word文件中提取文本.doc，docx，.xlsx，.pptx php

Question

可能有一種情況，我們需要從Word文檔中獲取文本以供將來使用，以便在用戶上傳的文檔中搜索字符串在cv的/簡歷中搜索，發生如何獲取文本，打開和閱讀用戶上傳的Word文檔的常見問題，有一些有用的鏈接，但不能解決整個問題。我們需要在當時獲取文本上傳並保存數據庫中的文本，我們可以輕鬆地在數據庫中進行搜索。

Answer 1

這是一個簡單的類，它爲.doc/.docx， PHP docx reader: Convert MS Word Docx files to text執行正確的工作。

class DocxConversion{ 
    private $filename; 

    public function __construct($filePath) { 
     $this->filename = $filePath; 
    } 

    private function read_doc() { 
     $fileHandle = fopen($this->filename, "r"); 
     $line = @fread($fileHandle, filesize($this->filename)); 
     $lines = explode(chr(0x0D),$line); 
     $outtext = ""; 
     foreach($lines as $thisline) 
      { 
      $pos = strpos($thisline, chr(0x00)); 
      if (($pos !== FALSE)||(strlen($thisline)==0)) 
       { 
       } else { 
       $outtext .= $thisline." "; 
       } 
      } 
     $outtext = preg_replace("/[^a-zA-Z0-9\s\,\.\-\n\r\t@\/\_\(\)]/","",$outtext); 
     return $outtext; 
    } 

    private function read_docx(){ 

     $striped_content = ''; 
     $content = ''; 

     $zip = zip_open($this->filename); 

     if (!$zip || is_numeric($zip)) return false; 

     while ($zip_entry = zip_read($zip)) { 

      if (zip_entry_open($zip, $zip_entry) == FALSE) continue; 

      if (zip_entry_name($zip_entry) != "word/document.xml") continue; 

      $content .= zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)); 

      zip_entry_close($zip_entry); 
     }// end while 

     zip_close($zip); 

     $content = str_replace('</w:r></w:p></w:tc><w:tc>', " ", $content); 
     $content = str_replace('</w:r></w:p>', "\r\n", $content); 
     $striped_content = strip_tags($content); 

     return $striped_content; 
    }

    public function convertToText() { 

     if(isset($this->filename) && !file_exists($this->filename)) { 
      return "File Not exists"; 
     } 

     $fileArray = pathinfo($this->filename); 
     $file_ext = $fileArray['extension']; 
     if($file_ext == "doc" || $file_ext == "docx" || $file_ext == "xlsx" || $file_ext == "pptx")

      } 
     } else { 
      return "Invalid File Type"; 
     } 
    } 

} 

Document_file_format文件是二進制文件blobs.They可以通過使用fopen。而.DOCX文件讀取只是ZIP文件和XML文件xml files in a zipfile container (source wikipedia)您可以通過使用zip_open閱讀。

使用上面的類

$docObj = new DocxConversion("test.doc"); 
//$docObj = new DocxConversion("test.docx"); 
//$docObj = new DocxConversion("test.xlsx"); 
//$docObj = new DocxConversion("test.pptx"); 
echo $docText= $docObj->convertToText(); 

Answer 2

的從DOC文件

$filename = 'ypue file';   
    if (file_exists($filename)) {   

    if (($fh = fopen($filename, 'r')) !== false) { 

    $headers = fread($fh, 0xA00); 

    $n1 = (ord($headers[0x21C]) - 1); 

    $n2 = ((ord($headers[0x21D]) - 8) * 256); 

    $n3 = ((ord($headers[0x21E]) * 256) * 256); 

    $n4 = (((ord($headers[0x21F]) * 256) * 256) * 256); 


    $textLength = ($n1 + $n2 + $n3 + $n4); 

    $extracted_plaintext = fread($fh, $textLength); 

    echo nl2br($extracted_plaintext); 

    print_r(extract_emails_from($extracted_plaintext));  

     } 

     } 

    function extract_emails_from($string) { 
      preg_match_all("/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $string, $matches); 
      return $matches[0]; 
    } 

從DOCX：

/*Name of the document file*/ 
    $document = 'your file'; 

    /**Function to extract text*/ 
    function extracttext($filename) { 
     //Check for extension 
     $ext = end(explode('.', $filename)); 

    //if its docx file 
    if($ext == 'docx') 
    $dataFile = "word/document.xml"; 
    //else it must be odt file 
    else 
    $dataFile = "content.xml";  

    //Create a new ZIP archive object 
    $zip = new ZipArchive; 

    // Open the archive file 
    if (true === $zip->open($filename)) { 
     // If successful, search for the data file in the archive 
     if (($index = $zip->locateName($dataFile)) !== false) { 
      // Index found! Now read it to a string 
      $text = $zip->getFromIndex($index); 
      // Load XML from a string 
      // Ignore errors and warnings 
      $xml = DOMDocument::loadXML($text, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING); 
      // Remove XML formatting tags and return the text 
      return strip_tags($xml->saveXML()); 
     } 
     //Close the archive file 
     $zip->close(); 
    } 

    // In case of failure return a message 
    return "File not found"; 
} 

echo extracttext($document); 

Answer 3

對於DOCX文檔，我建議使用docx2txt工具（可至少在Debian/Ubuntu）：

docx2txt < your_file.docx 

README解釋如何將它與vim集成。添加到你的.vimrc：

" use docx2txt.pl to allow VIm to view the text content of a .docx file directly. 
autocmd BufReadPre *.docx set ro 
autocmd BufReadPost *.docx %!docx2txt 

（它也解釋瞭如何與emacs集成）。

對於黑客來說，這個工具是用perl編寫的。
