php对gzip文件或者字符串解压实例参考_PHP

<br>if (!function_exists('gzdecode')) {      <br>    function gzdecode ($data) {      <br>        $flags = ord(substr($data, 3, 1));      <br>        $headerlen = 10;      <br>        $extralen = 0;      <br>        $filenamelen = 0;      <br>        if ($flags & 4) {      <br>            $extralen = unpack('v' ,substr($data, 10, 2));      <br>            $extralen = $extralen[1];      <br>            $headerlen += 2 + $extralen;      <br>        }      <br>        if ($flags & 8) // Filename      <br>            $headerlen = strpos($data, chr(0), $headerlen) + 1;      <br>        if ($flags & 16) // Comment      <br>            $headerlen = strpos($data, chr(0), $headerlen) + 1;      <br>        if ($flags & 2) // CRC at end of file      <br>            $headerlen += 2;      <br>        $unpacked = @gzinflate(substr($data, $headerlen));      <br>        if ($unpacked === FALSE)      <br>              $unpacked = $data;      <br>        return $unpacked;      <br>     }      <br>} <br> <br>调用方法很简单：  <br><u></u> 代码如下:<pre class="brush:php;toolbar:false layui-box layui-code-view layui-code-notepad"><ol class="layui-code-ol"><li><br>$f=@file_get_contents("http://www.bitsCN.com");       <br>echo gzdecode($f);                    </li></ol></pre>
