php：使用dns_get_record获取特定端口的SRV记录

Question

I configured this SRV records for my domain for my minecraft server (port 225565)

This works for minecraft itself. The new server url is mc.marc.tv:

BUT my monitor script in php does not find the SRV record:

<?php
$record = dns_get_record('_minecraft._tcp.mc.marc.tv');
var_dump($record);
?>

This is empty. But dig on my shell

dig SRV _minecraft._tcp.mc.marc.tv

returns this:

; <<>> DiG 9.10.6 <<>> SRV _minecraft._tcp.mc.marc.tv

What did I do wrong? How do I get the SRV record for this subdomain with php for a specific port only? Or did i configure the server wrong?
