Question

i have a multidimensional array
the first two statements of code work fine… notice them below…

      echo $arrayObjects['name'].'<br>';
      echo $arrayObjects['ipv4']['10.14.2.22']['type'].'<br>';

but i want to be able to return the keys in the ipv4 array, instead of having to hard code them like i did above. when i do the following:

      print_r( array_keys($arrayObjects['ipv4'])); 

I get the following output:

         Array ( [0] => 10.14.2.22 ) 

which is great. but how do i get the ip address returned to me as a variable?

Answer 1

Try:

First Element:

$ip_address = array_shift(array_keys($arrayObjects['ipv4']));

Each Element:

foreach($arrayObjects['ipv4'] as $ip_address => $value){
    print_r($ip_address);
}
