dns_get_record(): A temporary server error occurred.
提问by Josh Undefined
I'm querying a whole bunch of addresses, some are online and some are not. I can't seem to get around this error however, even catching the exception fails :(
我正在查询一大堆地址，有些在网上，有些不在。但是，我似乎无法解决此错误，即使捕获异常也失败了:(
dns_get_record(): A temporary server error occurred.
try {
$result = dns_get_record('_minecraft._tcp.' . $addr, DNS_SRV);
}
catch (Exception $e) {
return [$addr,$port];
}
If this error occurs, I want to continue the script, skipping the record, however currently the script just halts.
如果发生此错误，我想继续脚本，跳过记录，但目前脚本只是停止。
Any help appreciated!!

I can't catch this exception too. And how I understood it's a bug of php: https://bugs.php.net/bug.php?id=73149
我也无法捕捉到这个异常。我如何理解它是 php 的错误：https: //bugs.php.net/bug.php?id =73149
But I found another solution. You can use @when you call this function. This symbol kill all errors when you call this one. And it will looks like that:
但我找到了另一个解决方案。@调用此函数时可以使用。当您调用此符号时，此符号会消除所有错误。它看起来像这样：
$dns = @dns_get_record($domain, DNS_A);
if(!$dns){
return false;
}

try this:
尝试这个：
try {
$dns = dns_get_record($domain, DNS_A);
}
catch (Exception $e) {
if ($e->getMessage() !== 'dns_get_record(): A temporary server error occurred.') {
throw $e;
}
$dns = false;
}
