php openoffice转pdf的方法：首先下载“openoffice4.1.2”；然后将用户的访问权限为“允许”，并将标识调整为交互式；最后在php环境下运行代码为“function MakePropertyValue(){}”即可。

php操作openoffice把文件转换成pdf
1.上官网, http://www.openoffice.org。下载openoffice4.1.2
2.设置权限
cmd 运行Dcomcnfg.exe->组件服务->计算机->我的电脑->DCOM配置->OpenOffice Service Manager
3.打开openoffice 在进程中查看打开此进程的用户是谁 然后设置此用户的访问权限为允许；
然后将标识调整为交互式；
4.在php环境下运行此代码
Bridge_GetStruct("com.sun.star.beans.PropertyValue");
$oStruct->Name = $name;
$oStruct->Value = $value;
return $oStruct;
}
function word2pdf($doc_url, $output_url){
//Invoke the OpenOffice.org service manager
$osm = new COM("com.sun.star.ServiceManager") or die ("Please be sure that OpenOffice.org is installed.\n");
//Set the application to remain hidden to avoid flashing the document onscreen
$args = array(MakePropertyValue("Hidden",true,$osm));
//Launch the desktop
$top = $osm->createInstance("com.sun.star.frame.Desktop");
//Load the .doc file, and pass in the "Hidden" property from above
$oWriterDoc = $top->loadComponentFromURL($doc_url,"_blank", 0, $args);
//Set up the arguments for the PDF output
$export_args = array(MakePropertyValue("FilterName","writer_pdf_Export",$osm));
//Write out the PDF
$oWriterDoc->storeToURL($output_url,$export_args);
$oWriterDoc->close(true);
}
$doc_file = "file:///D:/wamp/www/study/phpr/201701/11.doc";
$output_file = 'file:///D:/wamp/www/study/phpr/201701/11.pdf';
word2pdf($doc_file,$output_file);
?>注意： 易错点：
1.php首先得开启com组件
php5.45之前在php.ini设置com.allow_dcom = true
php5.45之后extension=php_com_dotnet.dll
2.doc_file和output_file路径必须严格要求为
file:///D:/wamp/www/study/phpr/201701/11.pdf
