本文介绍如何使用PHP的gzinflate函数解压缩数据，并提供了一个Java程序示例来实现类似的功能，包括Base64解码和解压缩。

php 的gzinflat功能：

1
<?php
eval(gzinflate(base64_decode('7H35m9rItejPd75v/gfSmRvb10uztpvx2Ak7Er

2
...bla
 bla bla.... RGpn/Aw==')));?>

java实现

main(String[] args) throws

Exception {

15
        Scanner
 scanner = new

Scanner(new

16
        String

17
        InputStream
 inflInstream = new

InflaterInputStream(

18
                new

ByteArrayInputStream(new

Base64().decode(isi)),

19
                new

Inflater(true));//标准不一样

20
        byte

bytes[] = new

byte[4096];

21
         
22
        FileOutputStream
 fileOutputStream = new

FileOutputStream(new

File("decoded.txt"));

23
         
24
        while

(true)
 {

25
            int

length = inflInstream.read(bytes, 0,
4096);

26
            if

(length == -1)
 {

27
                break;

28
            }

29
            fileOutputStream.write(bytes,
0,
 length);            

30
        }

31
        fileOutputStream.flush();

32
        fileOutputStream.close();

33
    }
