PHP Extensions Programming

This is a very short job to program a php extension (.dll) for MS Windows. What I need is a php extension which allows php code to be filtered through the extension e.g. the php script will look something like this, and will automatically print the output from PHP: The php extension will have the same functionality as the 'eval' command integrated into php, but this must be integrated into a php extension as well. The php extension will have a function called 'PHP_FUNCTION(passCode)' The php extension will be programmed in C, and will be compiled using Visual C++. I can provide the basis code for programming this project, but I am having difficulties returning the output from PHP, this is because PHP is unidirectional, not bidirectional, anyone familiar with PHP will understand what I am saying here. I hesitate this project to be no longer than one hours work if you have created PHP extensions before. The successful candidate MUST have experience programming PHP extensions. If you have any questions regarding this project, or would like to see the outline source code for the PHP extension, please contact me.
