PHP调用OpenOffice实现word转PDF的方法

xgnic

            最近一直在研究PHP word文档转PDF，也在网上搜索了很多类似的资料，大多数都是通过OpenOffice进行转换的。
核心的代码如下：
function MakePropertyValue($name,$value,$osm){
  $oStruct = $osm->Bridge_GetStruct("com.sun.star.beans.PropertyValue");
  $oStruct->Name = $name;
  $oStruct->Value = $value;
  return $oStruct;
}
function word2pdf($doc_url, $output_url){
  $osm = new COM("com.sun.star.ServiceManager") or die ("lease be sure that OpenOffice.org is installed.n");
  $args = array(MakePropertyValue("Hidden",true,$osm));
  $oDesktop = $osm->createInstance("com.sun.star.frame.Desktop");
  $oWriterDoc = $oDesktop->loadComponentFromURL($doc_url,"_blank", 0, $args);
  $export_args = array(MakePropertyValue("FilterName","writer_pdf_Export",$osm));
  $oWriterDoc->storeToURL($output_url,$export_args);
  $oWriterDoc->close(true);
}
$doc_file=dirname(__FILE__)."/11.doc"; //源文件，DOC或者WPS都可以
$output_file=dirname(__FILE__)."/11.pdf"; //欲转PDF的文件名
$doc_file = "file:///" . $doc_file;
$output_file = "file:///" . $output_file;
$document->word2pdf($doc_file,$output_file);
