Description: ------------ With some combinations of mod_php and Apache, getlastmod() returns the access time instead of the modification time. All bug reports that deal with this seem to have been closed with "Works in CVS" or "Apache problem", both of which are not true. The Problem occurs if Apache was built with large file size (64-bit) support and mod_php wasn't, so they are essentially using different stat(2) structures. If 64-bit file offsets are used, the st_blocks member of struct stat grows to 64 bits and pushes the time members 32 bits "upwards". If you access this structure as a 32-bit stat structure from mod_php, st_atime contains garbage, st_mtime the access time and st_ctime the modification time of the 64-bit structure (voila!). The easy solution is to #define _FILE_OFFSET_BITS to 64, if Apache does (did) this. The hard part is that I don't know how to figure out if Apache uses 32 or 64 bits after it is installed. Secondly, PHP itself would have to use 64-bit stat structures, and I don't know if this might lead to more problems. So maybe it's better to transform the stat structure in mod_php?
