PHP也可以实现导出Word文档为PDF的功能，不过要借助于第三方的类库，今天我们将为大家介绍PHP依靠com.sun.star.ServiceManager来转换Word为PDF文档的相关技巧。
PHP处理Word转PDF的示例代码：
<?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 ("请确认OpenOffice.org库是否已经安装.\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 = "D:/temp/";
$doc_file = "D:/temps/test.doc";
$pdf_file = "test.pdf";
$output_file = $output_dir.$pdf_file;
$doc_file = "file:///".$doc_file;
$output_file = "file:///".$output_file;
word2pdf($doc_file,$output_file);
?>
