Description
string
bzcompress ( string source [, int blocksize [, int workfactor]])
bzcompress() compresses the
source string and returns it as bzip2
encoded data.
The optional parameter 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. blocksize defaults to
4.
The optional parameter workfactor 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 and 30 being the default
value. Regardless of the workfactor, the
generated output is the same.
Example 1. bzcompress() Example <?php
$str = "sample data";
$bzstr = bzcompress($str, 9);
print( $bzstr );
