title: php find greater of two numbers
body: <p>I am a straight novice in PHP. So, please do not down vote my question as it may seem very silly. I have a code to check if a number is greater than another number in php. </p>
  
  <pre><code>if($num1 &gt; $num2)
  {
      echo $num1
  }
  else
  {
      echo $num2
  }
  </code></pre>
  
  <p>The above code is the exact one in my file. But no output is being shown. Any help will be appreciated.</p>
