title: Recursion in PHP
body: <p>I have a function like this:</p>
  
  <pre><code>function test($T0){
    $T01 = $T0-$T0/2;
    $T02 = $T0+$T0/2;
    if($T01&lt;$T0){
      test($T01);
    } else if($T02&lt;$T0){
      test($T02);
    } else {}
    $result = array($T01,$T02);
      return $result;
    }
  
    $T0 = 50;
    $result = test($T0);
    echo $result[0];
  </code></pre>
  
  <p>Why this function is not recursion?</p>
