Mimetype Functions
I also had issues with this function.
The issue was that it would almost always return "text/plain".
echo ini_get('mime_magic.magicfile'); // returns /etc/httpd/conf/magic
I found that I needed the OS' magic.mime file instead.
You can either copy it to the existing location, or update your php.ini, you cannot use ini_set().
[root@blade conf]# mv magic magic.old
[root@blade conf]# cp /usr/share/magic.mime magic
[root@blade conf]# apachectl graceful
Note: you will see that I have gracefully restarted apache to ensure it has taken affect.
mime_content_type
(PHP 4 >= 4.3.0, PHP 5)
mime_content_type — Detect MIME Content-type for a file (deprecated)
Description
string mime_content_type
( string $filename
)
Returns the MIME content type for a file as determined by using information from the magic.mime file.
Parameters
- filename
-
Path to the tested file.
Return Values
Returns the content type in MIME format, like text/plain or application/octet-stream.
Notes
Warning
This function has been deprecated as the PECL extension Fileinfo provides the same functionality (and more) in a much cleaner way.
Examples
Example #1 mime_content_type() Example
<?php
echo mime_content_type('php.gif') . "\n";
echo mime_content_type('test.php');
?>
The above example will output:
image/gif text/plain

I cleaned up and compiled together code from different people here below. This code returns "unknown/<filesuffix>" if it can't something better.
<?php
function returnMIMEType($filename)
{
preg_match("|\.([a-z0-9]{2,4})$|i", $filename, $fileSuffix);
switch(strtolower($fileSuffix[1]))
{
case "js" :
return "application/x-javascript";
case "json" :
return "application/json";
case "jpg" :
case "jpeg" :
case "jpe" :
return "image/jpg";
case "png" :

Regarding serkanyersen's example : It is advisable to change the regular expression to something more precise like
preg_match("|\.([a-z0-9]{2,4})$|i", $filename, $m);
This makes sure that only the last few characters are taken. The original expression would not work if the filename is a relative path.

I've written an alternative for this. Not necessarily tested but it works OK on my server.
I hope this helps

preg_match("/\.(.*?)$/", $filename, $m); # Get File extension for a better match
switch(strtolower($m[1])){
case "js": return "application/javascript";
case "json": return "application/json";
case "jpg": case "jpeg": case "jpe": return "image/jpg";
case "png": case "gif": case "bmp": return "image/".strtolower($m[1]);
case "css": return "text/css";
case "xml": return "application/xml";
case "html": case "htm": case "php": return "text/html";

$m = mime_content_type($filename);
}else if(function_exists("")){ # if Pecl installed use it
$finfo = finfo_open(FILEINFO_MIME);
$m = finfo_file($finfo, $filename);
finfo_close($finfo);

Since I enabled the mime_magic extension on my IIS, I also got the error message "invalid magic file, disabled" in my phpinfo. After I add these lines to my php.ini, the message disappeared and it works great!
mime_magic.debug = Off
mime_magic.magicfile ="D:\PHP5\extras\magic.mime"
mime_magic.debug is by default off but without this line it fails. I'm using PHP 5.2.5.

For me mime_content_type didn't work in Linux before I added
mime_magic.magicfile = "/usr/share/magic.mime"
to php.ini (remember to find the correct path to mime.magic)

<?PHP

$ext=array_pop(explode('.',$file));
foreach(file('/usr/local/etc/apache22/mime.types') as $line)
if(preg_match('/^([^#]\S+)\s+.*'.$ext.'.*$/',$line,$m))

Not perfect, but works good enough for me ;)

The correct little correction:
exec will return the mime with a newline at the end, the trim() should be called with the result of exec, not the other way around.
<?php
if ( ! function_exists ( 'mime_content_type ' ) )
{
function mime_content_type ( $f )
{
return trim ( exec ('file -bi ' . escapeshellarg ( $f ) ) ) ;
}
}
?>

if you use a transparent 'spacer' GIF i've found it needs to be a around 25x25 for it to register as 'image/gif'. otherwise it's read in as 'text/plain'.

Completing <some dude AT somewhere DOT com> comment:
0 string < ? php application/x-httpd-php
and string detection on text files may fail if you check a file encoded with signed UTF-8. The UTF-8 signature is a two bytes code (0xFF 0xFE) that prepends the file in order to force UTF-8 recognition (you may check it on an hexadecimal editor).

The 'file' utility fortunately is available for Windows, too:

I added these two lines to my magic.mime file:
0 string \<?php application/x-httpd-php
0 string \<?xml text/xml
The first one may not work if "<?php" is not at the very beginning of your file, e.g., if some HTML preceeds the first bit of PHP code. The second one should work because "<?xml" *should* be the first thing in every XML file.
0 string \<?php application/x-httpd-php
0 string \<?xml text/xml
The first one may not work if "<?php" is not at the very beginning of your file, e.g., if some HTML preceeds the first bit of PHP code. The second one should work because "<?xml" *should* be the first thing in every XML file.

The function mime_content_type only worked for me on Microsoft Windows after I added the directive "mime_magic.debug" to my php.ini with the value of "On". The default value appears to be "Off". Exampe:
[mime_magic]
mime_magic.debug = On
mime_magic.magicfile = "c:\php\extras\magic.mime"
