Since it costed me some time to find the needed magic database files for Windows, just a hint:



The last release of the GnuWin32 project with both needed files (magic and magic.mime) currently was "file-4.23".

All releases after 4.23 to 4.25-1 did not contain both needed files.



Hope that helps.

Platform: WinXP-SP2, PHP5.2.5, MySQL 5.0, Apache 2.2.8



After reading former notes, I wasn't able to load my magic database: 'magic.mime' file (donwloaded from GnuWin32 project, zipped with the binary files v4.21). I always got an invalid $finfo object or finfo_open(...) returned FALSE.



In order to be able to load the 'magic.mime' file, Fileinfo library (bundled in PHP5.2.5) also requires 'magic' file.



For example:

1. Database:

  c:\php\magic.mime

  c:\php\magic



2. PHP Code:

<?php

  $filname = 'c:\php\php.ini';

  $finfo = new finfo(FILEINFO_MIME, 'c:\php\magic');

  if (!$finfo) return false;

  echo $finfo->file($filename);

?>

Pay attention to comments added by 'christophe dot charron dot xul at gmail dot com'



NOTE: Before upgrading to PHP5.2.5, I was working with PHP5.2.1 and it only required 'magic.mime' file.

The current version (1.04) doesnt support a different mime.magic database than the server default.



(the documentation is thus not correct)

Ubuntu default location is '/usr/share/file/magic'. In order for the examples to work all finfo_open()-commands must be issued with the extra location accordingly:

<?php

$file = "/path/to/file.jpg";

$handle = finfo_open(FILEINFO_MIME, '/usr/share/file/magic');

$mime_type = finfo_file($handle,$file);

?>

Couldn't get finfo to return the mimetype in the way expected so i made a function to do it with system()



<?php 

function get_mime_type($filepath) {

    ob_start();

    system("file -i -b {$filepath}");

    $output = ob_get_clean();

    $output = explode("; ",$output);

    if ( is_array($output) ) {

        $output = $output[0];

    }

    return $output;

}

?>



hope it works for other people too

Here is the exact link for Win32user to the file binary package:

On Windows systems people might find that this always returns "application/x-dpkg".

There are 2 ways of solving this problem:

1. Get the mime-magic database file from GnuWin32 at <http://sourceforge.net/projects/gnuwin32/>

2. You can manually "fix" the mime-magic file by editing it and escaping all lines starting with !, thus changing each one to \!
