How to read the compressed characters of PHP's Gzencode function output with Java

Phpjavagzdecode

The input string is PHP's Gzencode compressed string, which can be undone with Gzdecode, but is always prompted when reading a string in Java Java.util.zip.GZIPInputStream:
Java.util.zip.ZipException:Not in GZIP format
I hope that experienced friends to help me answer, my code is as follows:

 Javaimport Java.io.bytearrayinputstream;import Java.io.bytearrayoutputstream;import Java.io.InputStream;import Java.io.outputstream;import Java.util.zip.gzipinputstream;import Java.util.zip.gzipoutputstream;public Class Gzdecode {public static void decompress (InputStream is, OutputStream os) throws Exception {Gzipinpu        TStream GIS = new Gzipinputstream (IS);        int count;        byte data[] = new Byte[buffer];        while ((count = gis.read (data, 0, BUFFER))! =-1) {os.write (data, 0, count);    } gis.close (); } public static byte[] Decompress (byte[] data) throws Exception {Bytearrayinputstream Bais = new BYTEARRAYINP          Utstream (data);           Bytearrayoutputstream BAOs = new Bytearrayoutputstream ();           Decompression decompress (Bais, BAOs);          data = Baos.tobytearray ();          Baos.flush ();           Baos.close ();           Bais.close ();      return data; } public static void Main (string[]args) throws Exception {String input= "";        Byte[] Data=input.getbytes ("UTF-8");        Byte[] data_decompress=decompress (data); System.out.write (data_decompress);
