Introduction

Converting documents from various formats to PDF is crucial for combining files into a single document. This article will guide you through the process of converting Word and Excel files to PDF using PHP, without relying on the Zend Framework.

OpenOffice.org and PyODConverter

2. Download PyODConverter: Install this Python file (https://github.com/mirkonasato/pyodconverter) to facilitate the file conversion.

Conversion Script (adocpdf)

Create a plain text file named "adocpdf" containing the following script:

directory=
filename=
extension=
SERVICE='soffice'
if [ "`ps ax|grep -v grep|grep -c $SERVICE`" -lt 1 ]; then 
unset DISPLAY
/usr/bin/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard & 
sleep 5s
fi
python /home/website/python/DocumentConverter.py /home/website/$directory$filename$extension /home/website/$directory$filename.pdf

PHP Function

Call the conversion function from your PHP script when encountering a Word / Excel file:

$output = array();
$return_var = 0;
exec("/opt/adocpdf {$directory} {$filename} {$extension}", $output, $return_var);
