Format Output from Array

[partlyD]

Hi -

 

I am using dns_get_record():

 

$result = dns_get_record("google.com");
echo '<pre>';
print_r ($result);
echo '</pre>';

 

 

This returns:

 

Array
(
    [0] => Array
        (
            [host] => google.com
            [type] => SOA
            [mname] => ns1.google.com
            [rname] => dns-admin.google.com
            [serial] => 1416940

            [class] => IN
            [ttl] => 900
        )

    [5] => Array
        (
            [host] => google.com

            [target] => google.com.s9b1.psmtp.com
            [class] => IN
            [ttl] => 900
        )

 

 

I am new to php and would like to know what tools/commands I can use to go about manipulating and formatting the above output.  So for example, I can arrange the display of the output as:

 

google.com IN MX 100 google.com.s9a1.psmtp.com

google.com IN MX 200 google.com.s9a2.psmtp.com

google.com IN MX 300 google.com.s9b1.psmtp.com

 

etc...

 

Any help or information would be much appreciated.

foreach()

 

Should be all you need.

foreach()

 

Should be all you need.

 

Thank you for your reply.

 

When I use foreach:

 

<?php
$arr = dns_get_record("google.com");
reset($arr);
while (list($key, $value) = each($arr)) {
    echo "Key: $key; Value: $value<br />\n";
}

foreach ($arr as $key => $value) {
    echo "Key: $key; Value: $value<br />\n";
}
?>

 

 

The output shows the value of each as simply "Array":

 

Key: 0; Value: Array
Key: 1; Value: Array
Key: 2; Value: Array
Key: 3; Value: Array
Key: 4; Value: Array
Key: 0; Value: Array

The output shows the value of each as simply "Array":

 

This is because you have arrays within an Array.

 

I'll use the code you posted to help you better understand this.

Array
(
    [0] => Array
        (
            [host] => google.com
            [type] => SOA
            [mname] => ns1.google.com
            [rname] => dns-admin.google.com
            [serial] => 1416940
            [refresh] => 7200
            [retry] => 1800
            [expire] => 1209600
            [minimum-ttl] => 300
            [class] => IN
            [ttl] => 86400
        )

    [1] => Array
        (
            [host] => google.com
            [type] => TXT
            [txt] => v=spf1 include:_netblocks.google.com ip4:216.73.93.70/31 ip4:216.73.93.72/31 ~all
            [entries] => Array
                (
                    [0] => v=spf1 include:_netblocks.google.com ip4:216.73.93.70/31 ip4:216.73.93.72/31 ~all
                )

            [class] => IN
            [ttl] => 3600
        )

    [2] => Array
        (
            [host] => google.com
            [type] => MX
            [pri] => 400
            [target] => google.com.s9b2.psmtp.com
            [class] => IN
            [ttl] => 900
        )

    [3] => Array
        (
            [host] => google.com
            [type] => MX
            [pri] => 100
            [target] => google.com.s9a1.psmtp.com
            [class] => IN
            [ttl] => 900
        )

    [4] => Array
        (
            [host] => google.com
            [type] => MX
            [pri] => 200
            [target] => google.com.s9a2.psmtp.com
            [class] => IN
            [ttl] => 900
        )

    [5] => Array
        (
            [host] => google.com
            [type] => MX
            [pri] => 300
            [target] => google.com.s9b1.psmtp.com
            [class] => IN
            [ttl] => 900
        )

 

So if $result is the name of your variable, and you want to print the SOA record, you would need to do something like this:

echo $result[0][type];

That's because that record is in an array named '0' and the values of the array are what is printed inside f that array.

So,

echo $result[5][target];

 

Would print out: google.com.s9b1.psmtp.com.

Perfect!

 

Thanks for the clarification and taking the time.
