Re: [PHP] gzcompress/gzdeflate default compression level?
I think the default is 6, but you will need a very long string to get any benefit from higher numbers.

IIRC the default value is -1, which zlib currently converts to 6. > Thanks -- Evan Nemerson [EMAIL PROTECTED] -- "To think is to differ." -Clarence Darrow -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] gzcompress/gzdeflate default compression level?
The docs do not state what the defaults are, and from tests, it seems the values 4 - 9 return the same output as with no value, on the string I tested with.
