Question

<ul>
  <li>
     <a href='http://www.google.com'>Google</a>
  </li>
</ul>

And Here is my php code 

<?php 
  require_once('classes/simple_html_dom.php');
  $html = file_get_html("/var/www/html/dk/PHP_SCRAPPING/google.html");
  echo $html->find("ul li a",0)->href;
?>

You can't do that in PHP since all PHP code is executed server side and not client side. The PHP code doesn't run in a browser at all, so in essence there is no link to click.

If you want to script things client side, you'd need to resort to javascript. Although any sane browser won't let you emulate a click in Javascript for security reasons.

I think you need to read up on what exactly you're doing.

看看使用Python和Chrome / Firefox / PhantomJS Webdriver的Selenium，它可以让您完全控制单击任何网页中的任何按钮或链接..使用BeautifulSoup解析它，并且可以通过Python创建我们的json

If i am not getting you wrong you can do it with 2 option

  1. PHP -- header("Location:http://www.google.com");

  2. Javascript-- window.location("http://www.google.com");

Try 

echo $html->find("ul li a",0);

If that doesn't works you can do: 

echo "<a href='".$html->find("ul li a",0)->href."'>";
echo $html->find("ul li a",0)->plaintext."</a>";

I would use jQuery, I'm pretty sure you could do something like this. 

<head>
<script>      $("#clickable").click();         </script> 
</head>

<body> <?php  echo "<span id='clickable'>" . $html->find("ul li a",0)->href ."</span>";  ?>   </body>

Obviously you would need at add in the jquery library link and (doc.)ready... I haven't tested it but I don't see any reason why jQuery wouldn't click on a server side generated link
