Cause: Zlib introduces new constants ZLIB_ENCODING_RAW, ZLIB_ENCODING_GZIP, ZLIB_ENCODING_DEFLATE and redefines FORCE_GZIP as ZLIB_ENCODING_GZIP and FORCE_DEFLATE as ZLIB_ENCODING_DEFLATE. In php_http.c, line 263ff. the call to gzencode is prepared with an hard coded magic number (1) for the gzip encoding: gzencode(data, level, 1). It should be gzencode(data, level, FORCE_GZIP) or gzencode(data, level, ZLIB_ENCODING_GZIP), because the magic number is now defined as 0x1f (31). Test script: --------------- new SoapClient($wsdl, array('soap_version' => SOAP_1_2, 'compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 1 )); Expected result: ---------------- Call gzencode(data, level, FORCE_GZIP) (or gzencode(data, level, ZLIB_ENCODING_GZIP)), so it returns compressed data. Actual result: -------------- gzencode(data, level, 1) is called, so it returns always false and warns "encoding mode must be either ZLIB_ENCODING_RAW, ZLIB_ENCODING_GZIP or ZLIB_ENCODING_DEFLATE". ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61423&edit=1
