PHP function to generate .msg file for creating Outlook task

We have a web based PHP/MySQL task management application that we want to generate outlook tasks from the online tasks. I need a PHP function that can create a .msg format (or other format that I may not be familiar with that Outlook recognizes for tasks) from the online data. The goal is from the task view screen to have a button that calls the function that we can pass the MySQL data to that will create a temporary .msg file in a folder, which we will redirect to and the user can download, thereby creating a task on their instance of outlook. Requirements: Fully documented PHP function, file, or files that out program can call. Ability to change configuration for output path, data items used, etc. - base configuration should be all Outlook task fields: Subject Due Date Start Date Status Priority Percent Complete Owner??
