PHP's filesize() function returns the size of the file in bytes, which isn't very human-readable for anything over a few k.
So, if you find you are constantly performing calculations on filesizes to:
a) convert them to megs
b) round the value
... then this should help:
| <?php
function getFileSize($file,$round="1")
{
$bytes = 0;
if(file_exists($file))
{
$bytes = filesize($file);
}
$bytes = round($bytes/1000000,$round);
return $bytes;
}
?> | |
Usage Example:
So, for a 2572876 byte MP3 file....
| <?php
$file = "dir/dir/someFile.mp3";
$size = getFileSize($file,5); // 2.573
$size = getFileSize($file); // 2.6
?> | |
I've only included calculations for "meg" in the above example, but you can easily add to it to
calculate kb (1000 bytes), and even GB! |

Hello,
You have to do a correction in you division:
1 kB = 1024 bytes, 1 MB = 1024*1024 bytes and so on...
