Package php binaries + php script into one single executable file

Hi ! I would like to be able to "distribute" (freely) a single executable (binary) containing : - php binaries (v 5.3+) - a php script already packaged as a .phar (1 Mb, requiring PHP 5.3+) - additional (optional) compiled extensions - php.ini - all other resources required by the php executable to run The aim is to be able to provide a command line tool based on PHP but not requiring my user to install PHP *before* using the tool (and only download the tool as a single executable file to execute it) I would like my users to be able to use this "packaged" tool (requiring PHP 5.3+) whatever version of PHP my users have already installed (or not) on their system. Targeted platforms are : - windows (XP / Vista / 7) => 70% of my users - linux debian-like (ubuntu / debian) => 20% of my users - other platforms => 10% of my users At this point, this is not a problem for me to have a huge self-executable file (> 10Mb). I need to be able to package a version of the tool using a batch (or script), as I am using continuous integration. Do you have ideas on how to reach this goal ? The tool is open source, using New BSD License (currently, in beta version). Thanks for your answers ! Best regards, Olivier Hoareau
