Bug description:zlib.output_compression does not parse Accept-Encoding correct
Description:
------------
In ext/zlib/zlib.c:static PHP_FUNCTION(ob_gzhandler)
the HTTP_ACCEPT_ENCODING is not parsed.
PHP only checks, if the string "gzip" oder "deflate" is inside the
header and enables outputcompression if set.
RFC2616 allows for example that a probability (q) is set, which could be
also 0 (disable compression) but PHP will enable it.
For example:
Accept-Encoding: gzip;q=0.0
actual result: compressed output
expected result: uncompressed output
Accept-Encoding: thisisnotavalidgzipacceptencoding
actual result: compressed output
expected result: uncompressed output
Test script:
---------------
<?php
ini_set("zlib.output_compression", "1");
ob_start();
echo "foo";
ob_get_clean();
