Read and verify the map file
(PHP 4, PHP 5 <= 5.1.6)
Code Examples / Notes » filepro
Two notes here:
1) PHP does not need a running copy of filepro to read the datafiles. Just provide it with a directory containing the map file, key file, and the data* file(s) for the table you want to read. Screen files, outfiles, and process files are not used.
2) This function seems to pass back the system error code in brackets  along with the PHP warning. A list of error codes can be found in your filepro manual's appendix.
FYI: Please check for outstanding bug reports on the filepro functions before using them.
filepro() is apparently expecting the map file to be lowercase (at least on UNIX-like systems).
