title: Test if on a certain page with php?
body: <p>Using PHP, is there a way to test if the browser is accessing a certain page?</p>
  
  <p>For example, I have a header file called header.php which is being pulled into a couple different pages.  What I want to do is when I go to a different page, I want to append certain variable to the title.</p>
  
  <p>Example.</p>
  
  <p>Inside header.php:</p>
  
  <pre><code>&lt;?php 
  
  $titleA = " Online Instruction";
  $title B = "Offline";
  ?&gt;
  
  &lt;h2&gt;Copyright Info: &lt;?php if ('onlineinstruction'.php) echo $titleA; ?&gt; &lt;/h2&gt; 
  </code></pre>
  
  <p>edit: also if you believe there is  a simpler way to do this, let me know!</p>
