File Helper

A helper designed to manipulate files and filenames.

Methods

mime()

'mime' finds the MIME-type of a file first by using PHP's built-in database and then Kohana's MIME configuration file (system/config/mimes.php). The parameters are:

Example:

$file = 'my_movie.ogg'
echo $file.' ('.file::mime($file).')';
my_movie.ogg (application/ogg)

split()

'split' splits a file into pieces matching a specific size indicated in megabytes. The parameters are:

Example:

$file = 'humpty_dumpty.mp3'; // pretend it is 7.8 MB large
echo (file_exists($file)) ? file::split($file,FALSE,2) : 'can not find file!' ;
4

Directory listing:

-rwxrwxrwx 1 www-data www-data 8186302 2008-05-06 20:11 humpty_dumpty.mp3
-rw-r--r-- 1 www-data www-data 2097152 2008-05-06 20:15 humpty_dumpty.mp3.001
-rw-r--r-- 1 www-data www-data 2097152 2008-05-06 20:15 humpty_dumpty.mp3.002
-rw-r--r-- 1 www-data www-data 2097152 2008-05-06 20:15 humpty_dumpty.mp3.003
-rw-r--r-- 1 www-data www-data 1894846 2008-05-06 20:15 humpty_dumpty.mp3.004

join()

'join' joins splited files (possibly by file::split()), assuming a .### extension. The parameters are:

Example:

$file_in = 'humpty_dumpty.mp3'; // from our last example
$file_out = 'humpty_dumpty-back_together_again.mp3'; // output name
echo file::join($file_in,$file_out);
