title: Literal blank space in URL sent from GET request in PHP
body: <p>Howdie,</p>
  
  <p>being a noob i've tried to solve this on on my own but no result so far</p>
  
  <p>after creating this link in PHP: </p>
  
  <pre><code>&lt;a href ="edit_subject.php?subject=
                  &lt;?php echo $current_subject["id"]; ?&gt;"&gt;Edit Subject&lt;/a&gt;
  </code></pre>
  
  <p>the URL in Firefox shows a literal blank space in the browser like this:</p>
  
  <pre><code>edit_subject.php?subject=                1
  </code></pre>
  
  <p>everything works as it should but this really stumps me</p>
