print mime type

[Canman2005]

Hi all

 

I have the following;

 

$file = $_GET['filename'];

 

How can I print on screen, the mine type for this file?

 

Is this easy?

 

Thanks

Well first of all, using $_GET means you're accessing a querystring variable, so is your page being loaded such as myscript.php?filename=/path/to/somefile.onyourcomputer?  If so, use mime_content_type($file)

If you uploaded this file from a html form, this page will help

Hi

 

If I try that, I get the error

 

Fatal error: Call to undefined function mime_content_type() in C:\www\nagc\members\elements\download.php on line 3

 

Is there anymore options or what do I need to adjust or add?

 

Thankd

Nope, there files already stored on my server, this is for internal use so there is no security issue

<?php
$finfo = finfo_open(FILEINFO_MIME); // return mime type ala mimetype extension
echo finfo_file($finfo, $file);
finfo_close($finfo);
?>

With that one, I get

 

Fatal error: Call to undefined function finfo_open() in

 

Any ideas?

 

Thanks so far everyone

You have to install the extension first ( http://pecl.php.net/package/Fileinfo )

 

You also have the option to use the older mime_content_type

Hi

 

mime_content_type doesnt work on my server & im not able to install anything on it.

 

Is there no way around it, even with a complex function script?

 

I've hunted online but not found a script which works yet

 

Any advice anyone?

 

Thanks

If this is linux and exec is enabled then you can do something like

 

echo exec('file -i '.escapeshellcmd($filename));

Hi prozente

 

The server wont allow such a function, sadly I cant change any of the servers config and its all passworded up

 

Should I give up?

You could associate a MIME type with the file extensions.

There are pre-made classes that do this but the down side is it doesn't look at the content of the file to verify this.

You could create a script to look at the file header to determine the MIME but you'd have to research each file format and with the number of file types this could take some time.
