我有一个数组:
array (
[0] => Array (
[host] => google.nl
[class] => IN
[ttl] => 279310
[type] => NS
[target] => ns3.google.com)
[1] => Array (
[host] => google.nl
[class] => IN
[ttl] => 279310
[type] => NS
[target] => ns4.google.com)
[2] => Array (
[host] => google.nl
[class] => IN
[ttl] => 279310
[type] => NS
[target] => ns2.google.com)
这个数组是用dns_get_record ()
函数制作的。这是每个域的不同数量的变量。我如何与其他目标进行比较[0]['target']
,[1]['target']
以及[2]['target']
是否还有更多目标?
