Data exports w/ PHP & MySQL

I am trying to write a generic utility for exporting data from mysql and was hoping that I might be able to get some suggestions/ideas from some of the gods. My problem is that I have a several fixed-width file formats (specs) that I have to use when exporting data from mysql. This enables me to send the data out to an administrative group that makes use of the data in a system that is very stringent about what the file format must be. Some of the things that I have to keep in mind are: Field width for each column Starting point for each column Justification within the field (left or right justified) Some need to be zero filled I would like to use the file format as a config file or something to allow me the maximum amount of flexibility, because these formats change on a fairly regular basis. The following is a snippet from one of the file specs. Field Description..............Field Length.........Field Position Address-1...........................25....................190 Address-2...........................25.................... 215 City ....................................15.....................240 State.....................................2..................... 255 Zip Code............................10......................257 Phone.................................12......................267 Any suggestions/recommendations would be greatly appreciated. Thanks in advance. Glenn
