74364 Reverse engineer binary file

At a minimum, I need to reverse engineer the structure of a binary data file (example attached). The manufacturer of the program that creates this file also makes another program that will read and export the data contained in the binary file to a text file. A truncated export of the data contained within the attached file is included below. The ideal solution would be a PHP script that will read the data directly from the binary file to a multi-dimensional array and display the results of the array to the screen.
