File Helper

A helper designed to manipulate files and filenames.

'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:

• param: [string] filename to check MIME-type of
• return: [mixed] string if found, FALSE if not found

Example:

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

my_movie.ogg (application/ogg)

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

• param: [string] file to be split
• param: [string] directory to output to, defaults to the same directory as the file
• param: [integer] size, in MB, for each chunk to be
• return: [integer] The number of pieces that were created.

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!' ;

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

• param: [string] split filename, without .000 extension
• param: [string] output filename, if different then an the filename
• return: [integer] The number of pieces that were joined.

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);
