php中gzip對檔案或字串解壓縮的例子

/** * php自訂gzdecode解壓縮gzip檔案 * edit bbs.it-home.org */ if (!function_exists('gzdecode')) { function gzdecode ($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; } } ?> 複製代碼 調用： $f=@file_get_contents(http://bbs.it-home.org); echo gzdecode($f); ?> 複製代碼
