Downloading FileMaker API for PHP 1.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. This software for Mac OS X is an intellectual property of MacMedia. The program lies within Developer Tools, more precisely DB Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
