    Question Best way to iterate an array

    Hi

    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:

    1. userid
    2. phone type (work_phone, home_phone)
    3. mobile number




    PHP Code:
    $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?

    PHP Code:
            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";
                    }
                }
            }

    PHP Code:
    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 ";
          }

    PS - If you're posting here you should be using:

    error_reporting(E_ALL);
    ini_set('display_errors', '1');


    at the top of ALL php code while you develop it!

    My interpretation:
    PHP Code:
    <?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.
    --> JavaScript Frameworks like JQuery, Angular, Node <--
    ... and please remember to wrap code with forum BBCode tags:-

    [CODE]...[/CODE] [HTML]...[/HTML] [PHP]...[/PHP]

    If you can't think outside the box, you will be trapped forever with no escape...
