I have that because I have register globals turned off as compared to when I used to have it on, so instead of changeing every one of my pages to work with register globals off I just add that in

I'm a bit confused why your doing this:

<?php
  $global_vars = array(\"_GET\", \"_POST\");
  foreach($global_vars as $global_var)
    {
      $keys = array_keys($$global_var);
      foreach($keys as $key)
        {
          $$key = trim(${$global_var}[$key]);
        }
    }
?>

Try this instead:

<?php
extract($_GET);
extract($_POST);
?>

The uasort() in index.php isn't necessary. The one in data.php should be doing the job.

The problem here is that uasort() maintains index association. If you don't want this, you can substitute with usort(). You can still use uasort() and avoid this problem by using a foreach() loop() rather than a for() loop.

Try this for index.php:

<?php
<html>
  <head>
    <link rel=\"stylesheet\" type=\"text/css\" href=\"css/css.css\" />
    <title>Contact Phone Numbers</title>
  </head>
  <body>
    <table cellspacing=\"0\" cellpadding=\"0\" class=\"table-contacts\">
      <tr>
        <th>&nbsp;</th>
        <th>Last Name</th>
        <th>First Name</th>
        <th>Area</th>
        <th>Phone Number</th>
      </tr>

include(\"data.php\");
foreach ($contact_array as $key=>$contact) {
    echo \"<tr><td>\" . ($key) . \"</td>\";
    echo \"<td>\" . $contact[last_name] . \"</td>\";
    echo \"<td>\" . $contact[first_name] . \"</td>\";
    echo \"<td>\" . $contact[area_code] . \"</td>\";
    echo \"<td>\" . $contact[number] . \"</td></tr>\n\";
}

    </table>
  </body>
</html>
?>

Thanks for the code Mark but it's not working for me :S

I have this in data.php

<?php
//contacts array is here
  
  $global_vars = array(\"_GET\", \"_POST\");
  foreach($global_vars as $global_var)
    {
      $keys = array_keys($$global_var);
      foreach($keys as $key)
        {
          $$key = trim(${$global_var}[$key]);
        }
    }

  function sort_list($a, $b)
        {
          if (strtolower($a['first_name']) == strtolower($b['first_name'])) return 0;
          return (strtolower($a['first_name']) > strtolower($b['first_name'])) ? -1 : 1;
        }

  uasort($contact_array, 'sort_list');
  
  $max_contacts = count($contact_array);
?>

I have this in index.php

<?php
<html>
  <head>
    
      include(\"data.php\");
      for($i = 0; $i < $max_contacts; $i++)
              {
                $print_contacts .= \"<tr><td>\" . ($i + 1) . \"</td>\";
                $print_contacts .= \"<td>\" . $contact_array[$i][last_name] . \"</td>\";
                $print_contacts .= \"<td>\" . $contact_array[$i][first_name] . \"</td>\";
                $print_contacts .= \"<td>\" . $contact_array[$i][area_code] . \"</td>\";
                $print_contacts .= \"<td>\" . $contact_array[$i][area_code] . \" \" . $contact_array[$i][number] . \"</td></tr>\n\";
              }
    
    <link rel=\"stylesheet\" type=\"text/css\" href=\"css/css.css\" />
    <title>Contact Phone Numbers</title>
  </head>
  <body>
    <table cellspacing=\"0\" cellpadding=\"0\" class=\"table-contacts\">
      <tr>
        <th>&nbsp;</th>
        <th>Last Name</th>
        <th>First Name</th>
        <th>Area</th>
        <th>Phone Number</th>
      </tr>
      
        uasort($contact_array, 'sort_list');
        echo $print_contacts;
      
    </table>
  </body>
</html>
?>

I'm terrible at offering coding advice, so I'll just point you at php.net.
