Environment:
WAMP 5.0, WinXP, PHP 5.2.0, Apache 2.0
Whenever I run this function within SAPI PHP, though I have added this
line
to php.ini:
extension=php_fileinfo.dll
And restarted web services, class_exists('FileInfo') is always false,
furthermore, function_exists('finfo_open') is also always false
That I absolutely do not get
However, in CLI PHP, class_exists('FileInfo') is still false, however
function_exists('finfo_open') comes back true this time
But, if I try to use this line on a JPEG image:
echo finfo_file(finfo_open(FILEINFO_MIME, 'C:/wamp/php/extras/mime'),
'C:/images/blah.jpg');
I wind up instead of 'image/jpeg', this instead:
application/x-dpkg\015
Anyone who knows how to use FileInfo is welcome to play around with
the
function to make it fit, but it defaults to mime_content_type()
otherwise,
even though it's deprecated.
Thanks
Phil
