No, gzdeflate() implements rfc1951.
And rf2616 (http 1.1 specs) says "deflate : The "zlib" format defined in RFC 1950 [31] in combination with the "deflate" compression mechanism described in RFC 1951 [29]."
gzdeflate
(PHP 4 >= 4.0.4, PHP 5)
gzdeflate — Deflate a string
Opis
string gzdeflate
( string $data
[, int $level
] )
This function compress the given string using the DEFLATE data format.
For details on the DEFLATE compression algorithm see the document "» DEFLATE Compressed Data Format Specification version 1.3" (RFC 1951).
Parametry
- data
-
The data to deflate.
- level
-
The level of compression. Can be given as 0 for no compression up to 9 for maximum compression. If not given, the default compression level will be the default compression level of the zlib library.

Take care that that "PHP deflate" != "HTTP deflate".
The deflate encoding used in HTTP is actually zlib encoded.
This is what PHP functions return:
gzencode() == gzip
gzcompress() == zlib (aka. HTTP deflate)
gzdeflate() == *raw* deflate encoding

if you have compressed data which is greater than 2 MB (system dependent), you will receive a buffer error by calling the function gzinflate().
be sure to to compress your data by a lower compression level, like 1.
i.e.: gzdeflate($sData, 1);
