Fileinfo inconsistent, returning wrong MIME type

[comp.lang.php]

[PHP]
<pre>
if (!function_exists('mime_content_type_fileinfo')) {
/**
* Will use {@link http://us2.php.net/fileinfo FileInfo} functions
provided within {@link http://pecl.php.net PECL} bundle to return mime
type
*
* @param string $file
* @return string $mime_type
* @see mime_content_type
*/
function &mime_content_type_fileinfo($file) {
global $windowsMagicMimePath, $mimeTypeFilePath;
$mimePath = (($_ENV['windir'] || $_SERVER['windir']) &&
$windowsMagicMimePath) ? $windowsMagicMimePath : $mimeTypeFilePath;
if ($_ENV['windir'] || $_SERVER['windir']) $mimePath =
preg_replace('/\.mime$/i', '', $mimePath);
if (class_exists('FileInfo')) {
$finfo =& new FileInfo(FILEINFO_MIME, $mimePath);
if (is_object($finfo)) {
return $finfo->file($file);
} else if (function_exists('finfo_open')) {
$mime = finfo_file(finfo_open(FILEINFO_MIME, $mimePath), $file);
if ($mime) return mime; else return mime_content_type($file);
} else {
return mime_content_type($file);
}
} else if (function_exists('finfo_open')) {
$mime = finfo_file(finfo_open(FILEINFO_MIME, $mimePath), $file);
if ($mime) return $mime; else return mime_content_type($file);
} else {
return mime_content_type($file);
}
}
}
</pre>
[/PHP]

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

*update*

Ready for this one?

I did what was suggested: putting in "path" as both user and system
environmental variable, rebooted my machine.. NO PECL

Then I added the path to the PHP executable to both user and system
"path"
environmental variables, rebooted my machine.. STILL NO PECL

Then I finally decided to just "wing it". I tried everything my
imagination could deliver to me..

When I got to the part where I needed to add lines to wampserver.ini
to
recognize php_fileinfo.dll with the "on" option, I got PECL!

In fact, I found that through backward engineering the problem, that
there
was only one solution:

1) Have php_fileinfo.dll within PHP's php.ini
2) Have php_fileinfo.dll within Window's php.ini
3) Have php_fileinfo.dll within wampserver.ini

If any of these steps are not included, alongside the obvious web
services
restart, then PECL is not recognized.

In fact, I was able to get full PECL recognition even after I took out
the
"path" user defined environmental variable AND even after removing
the
paths to the PHP executable from the "path" system defined
environmental
variable!

Thanx all!
