title: What does a variable written immediately after "href=" do in html?
body: <p>I can't find a good explanation for this. What is the code after href= doing?</p>
  <p>The variable here$ is a URL. The variable result is a directory name.</p>
  <pre><code>echo &quot;&lt;h1&gt;&lt;a href=$here/$result&gt;$result&lt;/a&gt;&lt;/h1&gt;&quot;;
  </code></pre>
  <p>I understand this is html embedded in php. The echo gives it away.</p>
  <p>The question is, what is this:</p>
  <pre><code>href=$here/$result
  </code></pre>
  <p>I do not recognize this code in html.</p>
