Imagine we have an array like the following,

The values, 10, 20 are the userids. I want to send text messages to my users. What is the best way to iterate through this array to get the following:

userid
phone type (work_phone, home_phone)
mobile number

$data = array(
    '10' => array(
        'work_phone' => array(
            '9988776655', '7788665544'
        ),
        'home_phone' => array(
            '94455667733', '6655447733'
        )
    ),
    '20' => array(
        'home_phone' => array(
            '3333333333', '4444444444', '5555555555'
        )
    ),
);

I am doing it in the following way, is this the best approach?

		foreach ($data as $userID => $val) {
			foreach ($val as $type => $key) {
				foreach ($key as $number) {
					echo 'User ID is: ' . $userID, "\n";
					echo "Mobile Type is: " . $type, "\n";
					echo "Mobile number is: " .  $number, "\n\n\n";
				}
			}
		}

foreach ($data as $userid => $val)
{
      echo "User $userid has: \n";
      foreach ($val as $type=>$nums)
      {
          echo "$type is \n";
          foreach ($nums as $num)
              echo "$num ";
      }
}

My interpretation:

<?php

$data = array(
    '10' => array(
        'work_phone' => array(
            '9988776655', '7788665544'
        ),
        'home_phone' => array(
            '94455667733', '6655447733'
        )
    ),
    '20' => array(
        'home_phone' => array(
            '3333333333', '4444444444', '5555555555'
        )
    ),
);
echo "<ul>\n";
foreach($data as $userId => $numbers) {
	echo "<li>User # $userId\n<ul>\n";
	foreach($numbers as $type => $values) {
		echo "<li>".ucwords(str_replace('_', ' ', $type)).":\n<ul>";
		foreach($values as $nbr) {
			echo "<li>$nbr</li>\n";
		}
		echo "</ul>\n</li>\n";
	}
	echo "</li>\n</ul>\n";
}
echo "</ul>\n";

IMHO if you have a list of people then you should be using a database to pull your data from and then have the PHP send out the emails or SMS.

In all honesty, this smells like homework phishing.
