Description
stringint bzcompress(string $data, int $block_size = 4, int $work_factor = 0)
Parameters
-
data
-
The string to compress.
-
block_size
-
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.
-
work_factor
-
Controls how the compression phase behaves when presented with worst
case, highly repetitive, input data. The value can be between 0 and
250 with 0 being a special case.
Regardless of the work_factor, the generated
output is the same.
Return Values
The compressed string, or an error number if an error occurred.
