PHP - processing array values - php

Question

I have an array that contains DNS records and looks like this
Array ( [domain] => xxxx.com [record_id_+++711753] => 711753 [host_+++711753] => # [type_+++711753] => A [priority_+++711753] => [value_+++711753] => 80.82.72.12 [record_id_+++711752] => 711752 [host_+++711752] => www [type_+++711752] => A [priority_+++711752] => [value_+++711752] => 80.82.72.12 [record_id_+++711754] => 711754 [host_+++711754] => # [type_+++711754] => MX [priority_+++711754] => 20 [value_+++711754] => fallback.denit.net [record_id_+++711755] => 711755 [host_+++711755] => # [type_+++711755] => MX [priority_+++711755] => 10 [value_+++711755] => ms.denit.net [record_id_+++711756] => 711756 [host_+++711756] => mail [type_+++711756] => A [priority_+++711756] => [value_+++711756] => 62.148.185.22 [record_id_+++711757] => 711757 [host_+++711757] => autodiscover [type_+++711757] => CNAME [priority_+++711757] => [value_+++711757] => autoredirect.mshex.nl [record_id_+++1148031] => 1148031 [host_+++1148031] => webmail [type_+++1148031] => CNAME [priority_+++1148031] => [value_+++1148031] => webmail.mshex.nl )
_+++ is a delimiter between the record_id and the type of DNS value.
I need to talk to an API to update records. It works like this (example);
$mdr->addParam( "command", "dns_record_modify" );
$mdr->addParam( "domein", "xxx" );
$mdr->addParam( "tld", "com" );
$mdr->addParam( "record_id", "461741" );
$mdr->addParam( "host", "#" );
$mdr->addParam( "address", "mail2.xxx.com" );
$mdr->addParam( "priority", "20" );
I know that I can use explode to fill the API values, domain and TLD.
However I cant seem to find a way to group the array values by record_id and fire a request per record_id that combines multiple values like host, type and priority.
How should I achieve this?

Answer 1

You're correct about using the explode() method. IMO this is the best approach to the solution. I updated the answer because of the slight typo error and also added a working version. See it here.
# loop each entry
foreach($array as $key => $value)
{
# [0] - record_id
# [1] / $value - 711753
# check that the key isn't domain since it doesn't contain _++
if($key != 'domain')
{
$mdr->addParam(explode('_+++', $key)[0], $value);
}
else
{
$mdr->addParam($key,$value);
}
}
The above code snippet explodes the _+++ out of the key to find the callback value. The $value then holds the corresponding data callback and then each is passed through your instanced object in the method addParam().
Since the callback domain in your array keys does not contain the _+++ brace, I did a check before using the explode() method.

To group the array values by record_ids, you could create a new, multidimensional array and use the record IDs as top-level keys. Here's an example:
$data = array();
$data['domain'] = 'xxxx.com';
$data['record_id_+++711753'] = 711753;
$data['host_+++711753'] = '#';
$data['type_+++711753'] = 'A';
$data['type_+++1148031'] = 'CNAME';
$data['host_+++1148031'] = 'webmail';
$sorted_data = [];
foreach($data as $key=>$val){
$key_info = explode('_+++', $key);
if (count($key_info) > 1){
$record_id = $key_info[1];
$key_name = $key_info[0];
$sorted_data[$record_id][$key_name] = $val;
}
}
var_dump($sorted_data);

Answer 3

You could transform your data to another structure, and then produce the $mdr->addParam calls from that:
$domain = $data["domain"]; // "xxx.com"
$tld = end(explode(".", $domain)) "com"
$domain = substr($domain, count($domain)-count($tld)-1); // "xxx"
$updates = [];
foreach ($data as $key => $value) {
$parts = explode("_+++", $key);
if (count($parts) != 2) continue;
list($key, $rec) = $parts;
if ($key == "value") $key = "address";
$updates[$rec][$key] = $value;
}
$updates will be something like this:
Array(
[711753] => Array (
[record_id] => 711753
[host] => #
[type] => A
[priority] =>
[address] => 80.82.72.12
),
[711752] => Array (
[record_id] => 711752
[host] => www
[type] => A
[priority] =>
[address] => 80.82.72.12
),
...
Then from that, you continue:
foreach($updates as $update) {
$mdr = new .... // some code to create new instance
$mdr->addParam( "command", "dns_record_modify");
$mdr->addParam( "domein", $domain);
$mdr->addParam( "tld", $tld);
foreach($update as $key => $value) {
$mdr->addParam($key, $value);
}
// execute mdr ...
}
