mime_content_type

Detect MIME Content-type for a file (deprecated) (PHP 4 >= 4.3.0, PHP 5)
string mime_content_type ( string filename )

Example 1330. mime_content_type() Example

<?php
echo mime_content_type('php.gif') . "\n";

echo mime_content_type('test.php');
?>

The above example will output:

copy to clipboard

image/gif

text/plain

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"

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 ) ) ) ; } } ?>

The 'file' utility fortunately is available for Windows, too: http://gnuwin32.sourceforge.net/packages/file.htm

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'.

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.

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)

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).

<?php if (!function_exists('mime_content_type ')) { function mime_content_type($filename) { $finfo = finfo_open(FILEINFO_MIME); $mimetype = finfo_file($finfo, $filename); finfo_close($finfo); return $mimetype; } } ?>

<?PHP function qmimetype($file) { $ext=array_pop(explode('.',$file)); foreach(file('/usr/local/etc/apache22/mime.types') as $line) if(preg_match('/^([^#]\S+)\s+.*'.$ext.'.*$/',$line,$m)) return $m[1]; return 'application/octet-stream'; } ?> Not perfect, but works good enough for me ;)
