title: for loop from A - Z with PHP
body: <p>I can make the table perfectly if it's from A-Y but when it if I change it to 'Z', it won't work anymore.</p>
  
  <p>Does anybody know the problem?</p>
  
  <pre><code>&lt;table border="1"&gt;
  &lt;?php
  
      for($row=1; $row&lt;=22; $row++){
          echo "&lt;tr&gt;";
          for($column="A"; $column &lt;= "Y"; $column++){
              echo "&lt;td&gt; $row $column &lt;/td&gt;";
          }   
          echo "&lt;/tr&gt;";
      }
  ?&gt;
  &lt;/table&gt;
  </code></pre>
