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

这是一个简单的类，它为.doc / .docx，PHP docx阅读器做正确的工作：将MS Word Docx文件转换为文本。

    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;
    }

            }

            return "Invalid File Type";
        }
    }

}

Document_file_format文档文件是二进制 blob。可以使用 fopen 读取它们。虽然.docx文件只是zip文件和xml文件zml文件xml文件在zipfile容器（源维基百科），你可以使用zip_open来读取它们。

以上类的用法

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

从 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];
    }

来自 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);
