我试图找到一种计算.ppt / .pptx文件单词的方法,但无法弄清楚该怎么做。我通过下面的功能,但似乎没有工作:
function parsePPT($filename) {
$fileHandle = fopen($filename, "r");
$line = @fread($fileHandle, filesize($filename));
$lines = explode(chr(0x0f),$line);
$outtext = '';
foreach($lines as $thisline) {
if (strpos($thisline, chr(0x00).chr(0x00).chr(0x00)) == 1) {
$text_line = substr($thisline, 4);
$end_pos = strpos($text_line, chr(0x00));
$text_line = substr($text_line, 0, $end_pos);
$text_line = preg_replace("/[^a-zA-Z0-9\s\,\.\-\n\r\t@\/\_\(\)]/","",$text_line);
if (strlen($text_line) > 1) {
$outtext.= substr($text_line, 0, $end_pos)."\n";
}
}
}
return $outtext;
}
如果不直接从ppt输出文本中计算,它应该是一种以XML或其他格式转换它然后轻松输出文本的方法吗?
提前感谢您的帮助!
更新:以下函数为.PPTX文件执行作业,但.PPT:
function parsePPT($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;
}
