title: syntax error, unexpected '(', expecting variable (T_VARIABLE) or '$'
body: <p>I'm trying to build tabbed panels where a user can retain at current tab after refresh, updates etc. So, I'm trying to apply this script to my web as a tabbed panel but can't figure out what causes the syntax error. I've been trying to solve the problem for days regarding tabs but can seem to solve it. Btw, I don't use cookies and jquery. I don't use cookies because my friends (my clients) don't use cookies on their terminals. second, I don't use jquery (even though it's better) I prefer php only. please help thank you.</p>
  
  <pre><code>&lt;?php 
   $('ul.tabs').each(function(){
      // For each set of tabs, we want to keep track of
      // which tab is active and its associated content
      var $active, $content, $links = $(this).find('a');
      // If the location.hash matches one of the links, use that as the active tab.
      // If no match is found, use the first link as the initial active tab.
      $active = $($links.filter('[href="'+location.hash+'"]')[0] || $links[0]);
      $active.addClass('active');
      $content = $($active[0].hash);
      // Hide the remaining content
      $links.not($active).each(function () {
        $(this.hash).hide();
      });
      // Bind the click event handler
      $(this).on('click', 'a', function(e){
        // Make the old tab inactive.
        $active.removeClass('active');
        $content.hide();
        // Update the variables with the new link and content
        $active = $(this);
        $content = $(this.hash);
        // Make the tab active.
        $active.addClass('active');
        $content.show();
        // Prevent the anchor's default click action
        e.preventDefault();
      });
    }); ?&gt;
  &lt;html&gt;
  &lt;head&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;ul class='tabs'&gt;
      &lt;li&gt;&lt;a href='#tab1'&gt;Tab 1&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href='#tab2'&gt;Tab 2&lt;/a&gt;&lt;/li&gt;
      &lt;li&gt;&lt;a href='#tab3'&gt;Tab 3&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;
    &lt;div id='tab1'&gt;
      &lt;p&gt;Hi, this is the first tab.&lt;/p&gt;
    &lt;/div&gt;
    &lt;div id='tab2'&gt;
      &lt;p&gt;This is the 2nd tab.&lt;/p&gt;
    &lt;/div&gt;
    &lt;div id='tab3'&gt;
      &lt;p&gt;And this is the 3rd tab.&lt;/p&gt;
    &lt;/div&gt;
    &lt;/body&gt;
    &lt;/html&gt;
