First, trusting the mime-type from the client is very dangerous. On Fedora, the php-pear-Fileinfo package uses the same magic file that the command line file command uses. If you compile the fileinfo extension separately, you might be using a different magic file, which might provide inconsistent results. I have seen /usr/share/misc/magic ( default for fileinfo upstream ) and /usr/share/file/magic ( default for Fedora ). You also need to use the same flags or options. Using the PHP fileinfo functions, there are options you pass ( FILEINFO_MIME ) in order to get the output you want. Using the file command, there are flags you pass ( -i ) in order to get the output you want. The defaults are different between the two. For example, these options should give the same between <?php finfo_file() ?> and file from the command line - file -biLz filename finfo_file($finfo,"filename",1046) You need to add the integer values of the FILEINFO_* options -b is the default for finfo_file() -i == FILEINFO_MIME or 1040 -L == FILEINFO_SYMLINK or 2 -z == FILEINFO_COMPRESS or 4 -k == FILEINFO_CONTINUE or 32, which is mutually exclusive of FILEINFO_MIME That is, you can't use FILEINFO_CONTINUE and FILEINFO_MIME together, is is either one of the other. Sometimes using FILEINFO_CONTINUE and parsing that string gives you more information than FILEINFO_MIME does, but that parsing is harder and more complicated. if finfo_file($finfo,"filename",1040) returns a gzip or zip mime-type, you could then do finfo_file($finfo,"filename",1044) to see what type of data is inside that compressed file.
