bytes2human

string bytes2human(int bytes [, int precision]) -- Convert a number of bytes to human readable.

Description

Converts a number of bytes into a human readable format. The optional precision parameter decides the precision of the value returned. I admit to having written this way too confusing, but readability was put aside for a moment :)

Example

<?php echo "125926 is " . bytes2human(125926); ?>

This will output:

125926 is 122.97kB
