title: numbers and letters generator
body: <p>I have been looking for ages for a generator that would generate letter, numbers and symbols. For example, using either javascript or php, it would print out:</p>
  
  <pre><code>a 
  
  b 
  
  c
  </code></pre>
  
  <p>etc. etc. etc.</p>
  
  <pre><code>aa
  
  ab
  
  ac
  </code></pre>
  
  <p>etc. etc. etc.</p>
  
  <pre><code>aab
  
  aac
  
  aad
  </code></pre>
  
  <p>etc. etc. etc.</p>
  
  <p>I am horrible when it comes to any mathematical equations (I assume this would require Javascript as opposed to PHP).</p>
  
  <p>Does anyone know of either a generator or a website explaining how to do this. I tried googling it, but the terms I use keep having some random generators popping up :/</p>
  
  <p><strong>EDIT:</strong> I have found this code. Any suggestions in implementing symbols with it, as well as mixing everything up? For example, aB1@</p>
  
  <pre><code>&lt;?php
  $i = 'a';
  for ($n=0; $n&lt;200; $n++) {
      echo ++$i . '&lt;br/&gt;'. "\n";
  }
  ?&gt;
  </code></pre>
  
  <p>I modified it to this so far :/ missing quite a few things I know.</p>
  
  <ol>
  <li>-I have no clue how to add symbols in there.</li>
  <li>-Nor how to mix all of it correctly.</li>
  <li>-And I can't seem to start from A or 0</li>
  </ol>
  
  <p>modified code</p>
  
  <pre><code>&lt;?php
      $i = 'a';
      $m = '1';
      for ($n=0; $n&lt;200; $n++) {
          echo ++$i . ++$m . '&lt;br/&gt;'. "\n";
      }
      ?&gt;
  </code></pre>
