Description
bzcompress() compresses the given string and returns it as bzip2 encoded data.
Parameters
-
source -
The string to compress.
-
blocksize -
Specifies the blocksize used during compression and should be a number from 1 to 9 with 9 giving the best compression, but using more resources to do so.
-
