Description:
------------
zlib allows you to specify dictionaries to be used while inflating or deflating.  The php APIs are lacking this functionality.

Properly picked dictionaries can VASTLY improve your compression ratio.  My company is doing this, but I can't use PHP to access the database due to this missing feature in PHP's zlib API.
