title: PHP - How does the `require_once` construct executes the code?
body: <p>I am wondering which one of the following is a better approach when I call <code>require_once(file.php)</code>:</p>
  
  <p><code>file.php</code></p>
  
  <pre><code>&lt;?php
      $name = "Three";
      echo "&lt;h1&gt; Header Tag : $name &lt;/h1&gt;";
  ?&gt;
  </code></pre>
  
  <p>OR</p>
  
  <p><code>file.php</code></p>
  
  <pre><code>&lt;?php
     $name = "Three";
  ?&gt;
  
  &lt;h1&gt; Header Tag : &lt;?=$name?&gt; &lt;/h1&gt;
  </code></pre>
  
  <p>I'm curious to know if using either one of these could cause any sort of problem down the road in execution.</p>
