如何用PHP从Word文件(.doc, .docx, .xlsx, .pptx)中提取文本

phpms-worddocx.doc
56

可能存在这样的场景，我们需要从Word文档中获取文本以供未来使用，在用户上传的文档中查找字符串，例如在简历/履历中搜索，常见问题是如何获取文本，打开并读取用户上传的Word文档，有一些有用的链接但不能解决整个问题。我们需要在上传时获取文本并将其保存在数据库中，这样我们可以轻松地在数据库中进行搜索。

这是一个简单的类，可以很好地处理.doc/.docx文件， PHP docx阅读器：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;
    }

    public function convertToText() {

        {
            if($file_ext == "doc") {
                return $this->read_doc();
            } elseif($file_ext == "docx") {
                return $this->read_docx();
            } elseif($file_ext == "xlsx") {

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

}

文档文件格式 Doc文件是二进制数据，可以使用fopen读取。而.docx文件实际上是zip文件和xml文件（来源：维基百科），可以使用zip_open读取。

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();
谢谢你的精彩回答。 我正在尝试使用你的代码，但它不起作用。它显示为空，并且我认为我的"zip"函数没有工作。你能帮我找出问题所在吗？ - Mohammed Sufian

您可以使用 PHPOffice 在 PHP 中读取 docx 内容。
    $content = '';
    $phpWord = \PhpOffice\PhpWord\IOFactory::load($r->file);

    foreach($phpWord->getSections() as $section) {
        foreach($section->getElements() as $element) {
            if (method_exists($element, 'getElements')) {
                foreach($element->getElements() as $childElement) {
                    if (method_exists($childElement, 'getText')) {
                        $content .= $childElement->getText() . ' ';
                    }
                    else if (method_exists($childElement, 'getContent')) {
                        $content .= $childElement->getContent() . ' ';
                    }
                }
            }
            else if (method_exists($element, 'getText')) {
                $content .= $element->getText() . ' ';
            }
        }
    }

然后使用print_r函数打印$content，以查看其作为字符串的内容。

对于docx文档，我建议使用docx2txt工具（至少在Debian / Ubuntu上可用）：
docx2txt < your_file.docx

README 说明如何将其与 vim 集成。请在您的 .vimrc 中添加：

" 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

（它还解释了如何与emacs集成。）
对于黑客来说，这个工具是用perl编写的。
