PHP decompression of gzip files or strings example reference_PHP tutorial

In fact, php is very simple to decompress gzip. You can just use the built-in gzdecode function. However, unfortunately, I configured it for a long time and could not support the gzdecode function, so I had to work around it:

Copy code The code is as follows:

if (!function_exists('gzdecode')) {                                                  , 3, 1));                                                                            4) {                                                                                                                  'v' ,substr($data, 10, 2));                                                              
if ($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;
} 
}


The calling method is very simple:



Copy code

The code is as follows:

$f=@file_get_contents("http:/ /www.jb51.net");
