提示的时候就是这三行不停的循环输出，大概有几十上百行吧，页面卡死，我直接关掉浏览器

也不是每次都如此，大部分都是正常的，只是偶尔碰到连接的时候会出现这样的错误异常

x.php文件：

请问这几行代码有没有修改的可能？

------解决方案--------------------
$fp = fsockopen($server, 43, $errNo, $errStr, 10);
失败
应加上排错代码
------解决方案--------------------
fsockopen根本就没有打开abc.com
------解决方案--------------------
fsockopen() returns a file pointer which may be used together with the other file functions (such as fgets(), fgetss(), fwrite(), fclose(), and feof()). If the call fails, it will return FALSE


这么写 = =


$data = "";
$text = "xawasdf";
$server = "abc.com";
$fp = fsockopen($server, 43, $errNo, $errStr, 10);
if($fp)
{
fputs($fp, $text. "\r\n"); //100行
while (!feof($fp)) { //101行
$data .= fgets($fp, 128); //102行
}
fclose($fp);
}
------解决方案--------------------
你fputs参数传成了空句柄，原因是fopen失败造成返回内容(fputs的参数)异常
