title: How to traverse PHP Array from HTML TextArea Input?
body: <p>Whenever I receive input such as from a HTML Textarea box:</p>
  
  <pre><code> joeschmo@gmail.com:25wfsfrs
   johnbrown@yahoo.com:324dasd
   janedoe@yahoo.com:3dsadasd
  </code></pre>
  
  <p>I want to use the PHP function explode() on the colon and print out a list such as:</p>
  
  <pre><code>Usernames:
  1st Email
  2nd Email
  3rd Email
  
  Passwords:
  1st Pass
  2nd pass
  3rd Pass
  </code></pre>
  
  <p>Code so far:</p>
  
  <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;title&gt;
  Usernames AND Passwords!
  &lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
  
  &lt;?php
  /*Print contents of textarea for testing purposes.*/
  
  $data = explode("\n", $_POST['uandp']);
  foreach($data as $value){
      echo $value;
  }
  
  /*Split username and password*/
  $string = $_POST['uandp']; 
  list($string1,$string2) = explode(":",$string);  
  /*$string1 = username, $string2 = password*/ 
  $new_string = $string1;
  $new_string2 = $string2;
  /*$new_string = Username*/
  /*$new_string = Password*/
  
  echo $new_string;
  echo $new_string2;
  ?&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Not sure where to go from here. I know I have to store the textarea form data into an array and parse it from there.</p>
