本篇章节讲解php自定义类fsocket模拟post或get请求的方法。分享给大家供大家参考。具体如下： zsocket.class.php文件如下： _setCookie(substr($line,12)); }
$reHeader .= $line;
if(substr($line,16) == 'Content-Length: '){
$maxlen = intval(substr($line,16,-2));
}
if($line == "rn" || $line == "") break;
}

demo代码如下： get_HeaderInfo($host,$type,$file,$params);
$data = $zsk->get_SendData($host,$header);
/*
echo "rn";
*/
var_dump($header);
var_dump($data);
