PHP-Upload-Dateikonvertierung in PDF

Ich habe mehrere Tage online gesucht, um diese Funktion zu implementieren - -

Notizen!

Dies ist der Basiscode, aber Openoffice muss installiert sein.

‍<?php 
set_time_limit(0); 
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 ("Please 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); 
} 
$output_dir = "e:/word_pdf/"; 
$doc_file = "D:/Program Files/EasyPHP-5.3.3.1/www/mundi.ppt"; 
$pdf_file = "3.pdf"; 
$output_file = $output_dir . $pdf_file;
echo $doc_file;
$doc_file = "file:///" . $doc_file; 
$output_file = "file:///" . $output_file; 
word2pdf($doc_file,$output_file); 
?>
