title: "$x == $y" is true in PHP when $x and $y are "not equal"?
body: <p>I've been a developer for decades - in many programming languages. I can't get a very simple straight forward "if" statement to work in PHP:</p>
  
  <pre><code>if($groupminc == $groupmaxc)
  
      {
       echo "AFTER1:GROUPMIN==&gt;" . $groupminc . "\n";
       echo "AFTER1:GROUPMAX==&gt;" .  $groupmaxc . "\n";
       $groupmsg = $groupminc . " Participant";
      }
    else
     {
       echo "AFTER2:GROUPMIN==&gt;" . $groupminc . "\n";
       echo "AFTER2:GROUPMAX==&gt;" .  $groupmaxc . "\n";
       $groupmsg = $groupminc . " to " . $groupmaxc . " Participants";
     }
  </code></pre>
  
  <p>I'm getting the AFTER1 happening even when $groupminc and $groupmaxc are clearly <strong>not equal.</strong></p>
