如何从word文件中提取文本.doc，docx，.xlsx，.pptx php
可能有一种情况，我们需要从Word文档中获取文本以供将来使用，以便在用户上传的文档中searchstring，例如在cv / resumes中进行search，并发生如何获取文本，打开和阅读的常见问题用户上传的Word文档，有一些有用的链接，但没有解决整个问题。我们需要在上传时获取文本和保存在数据库中的文本，我们可以轻松地在数据库中search。
提问并回答你自己的问题是可以的
这是一个简单的类，它为.doc / .docx， PHP docx阅读器执行正确的工作：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 $striped_content; } /************************excel sheet************************************/ function xlsx_to_text($input_file){ $xml_filename = "xl/sharedStrings.xml"; //content file name $zip_handle = new ZipArchive; $output_text = ""; if(true === $zip_handle->open($input_file)){ if(($xml_index = $zip_handle->locateName($xml_filename)) !== false){ $xml_datas = $zip_handle->getFromIndex($xml_index); $xml_handle = DOMDocument::loadXML($xml_datas, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING); $output_text = strip_tags($xml_handle->saveXML()); }else{ $output_text .=""; } $zip_handle->close(); }else{ $output_text .=""; } return $output_text; } /*************************power point files*****************************/ function pptx_to_text($input_file){ $zip_handle = new ZipArchive; $output_text = ""; if(true === $zip_handle->open($input_file)){ $slide_number = 1; //loop through slide files while(($xml_index = $zip_handle->locateName("ppt/slides/slide".$slide_number.".xml")) !== false){ $xml_datas = $zip_handle->getFromIndex($xml_index); $xml_handle = DOMDocument::loadXML($xml_datas, LIBXML_NOENT | LIBXML_XINCLUDE | LIBXML_NOERROR | LIBXML_NOWARNING); $output_text .= strip_tags($xml_handle->saveXML()); $slide_number++; } if($slide_number == 1){ $output_text .=""; } $zip_handle->close(); }else{ $output_text .=""; } return $output_text; } public function convertToText() { if(isset($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" || $file_ext == "pptx") { if($file_ext == "doc") { return $this->read_doc(); } elseif($file_ext == "docx") { return $this->read_docx(); } elseif($file_ext == "xlsx") { return $this->xlsx_to_text(); }elseif($file_ext == "pptx") { return $this->pptx_to_text(); } } else { return "Invalid File Type"; } } } Document_file_format Doc文件是二进制的blob。他们可以通过使用fopen来读取。而.docx文件只是zip文件和xml文件在zipfile容器（源wikipedia）中的xml文件，您可以使用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]; }
从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);
//对于DOCX。如果你想保留空格，还要照顾表tr和tc，使用下面的代码：修改它的口味。 因为它从远程或本地下载文件

如果你使用Java，你可以使用Apache Tika 。 它可以从许多types的文件中提取文本。
对于docx文档，我build议使用docx2txt工具（至less在Debian / Ubuntu上）：
docx2txt < your_file.docx
README解释了如何将其与vim集成。 添加到您的.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
（这也解释了如何与emacs集成）。
对于黑客来说，这个工具是用perl编写的。
