title: How can I get the next letter alphabetically without incrementing? (php)
body: <pre><code>for ($i=A;$i&lt;L;$i++){                   
      echo $i;
      echo '-&gt;';
      echo ++$i;
      echo ', ';
  }
  </code></pre>
  
  <p>gives me:</p>
  
  <blockquote>
    <p>A->B, C->D, E->F, G->H, I->J, K->L</p>
  </blockquote>
  
  <p>what I want is:</p>
  
  <blockquote>
    <p>A->B, B->C, C->D, D->E, E->F, F->G</p>
  </blockquote>
  
  <p>What's the simplest way to do this?</p>
