fputs()出现异常怎么办?
页面提示:

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:

-->            $data = "";
            $text = "xawasdf";
            $server = "abc.com";
            $fp = fsockopen($server, 43, $errNo, $errStr, 10);
            fputs($fp, $text. "\r\n"); //100行
            while (!feof($fp)) { //101行
                $data .= fgets($fp, 128); //102行
            }
            fclose($fp);
Copy after login



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
