PHP加密了怎么解出来？

这个应该是gzip压缩。用个解压缩的就行。function gzip_decode ($data) {$flags = ord(substr($data, 3,

1));$headerlen = 10;$extralen = 0;$filenamelen = 0;if ($flags & 4) {$extralen = unpack('v' ,substr($data, 10,

2));$extralen = $extralen[1];$headerlen += 2 + $extralen;}if ($flags & 8) // Filename$headerlen = strpos($data, chr(0), $headerlen) + 1;if ($flags & 16) // Comment$headerlen = strpos($data, chr(0), $headerlen) + 1;if ($flags & 2) // CRC at end of file$headerlen += 2;$unpacked = @gzinflate(substr($data, $headerlen));if ($unpacked === FALSE)$unpacked = $data;return $unpacked;}
