可以使用一下PHPWord，要确保你的php版本是 PHP 5.3+

if($ext == 'docx'){
//docx文件可以直接读取
$contents = $this->extracttext($file);
}elseif($ext == 'doc'){
//doc文件，需要安装antiword软件来读取
$contents = shell_exec( "antiword -m UTF-8 $file" );
}else{
$contents = file_get_contents($file);
}

 function extracttext($filename) {
    $ext = end(explode('.', $filename));
    if($ext == 'docx')
        $dataFile = "word/document.xml";
    else
        $dataFile = "content.xml";
    $zip = new ZipArchive;
    if (true === $zip->open($filename)) {
        if (($index = $zip->locateName($dataFile)) !== false) {
            $text = $zip->getFromIndex($index);
            $xml = DOMDocument::loadXML($text, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING);
            return strip_tags($xml->saveXML());
        }
        $zip->close();
    }
    return false;
}
