    <title>CodeMirror: PHP+HTML+JavaScript+CSS mixed-mode demonstration</title>
    <link rel="stylesheet" type="text/css" href="../../css/docs.css"/>
  </head>
  <body style="padding: 20px;">

    <p>This is a complex demonstration of the <b>PHP+HTML+JavaScript+CSS mixed-mode
    syntax highlight</b> capabilities of <a href="../../index.html">CodeMirror</a>.
    &lt;?php ... ?> tags use the PHP parser, &lt;script> tags use the JavaScript
    parser, and &lt;style> tags use the CSS parser. The rest of the content is
    parsed using the XML parser in HTML mode.</p>

    <p>Features of the PHP parser:
    <ul>
      <li>special "deprecated" style for PHP4 keywords like 'var'
      <li>support for PHP 5.3 keywords: 'namespace', 'use'
      <li>911 predefined constants, 1301 predefined functions, 105 predeclared classes
        from a typical PHP installation in a LAMP environment
      <li>new feature: syntax error flagging, thus enabling strict parsing of:
        <ol>
          <li>function definitions with explicitly or implicitly typed arguments and default values
          <li>modifiers (public, static etc.) applied to method and member definitions
          <li>foreach(array_expression as $key [=> $value]) loops
        </ol>
      <li>differentiation between single-quoted strings and double-quoted interpolating strings
    </ul>
    </p>

The "root" parser is XML in HTML mode.
Next, we can switch into PHP mode, for example. This is
<?php echo 'text output by';
?>
PHP. </b>
On the line above, we just had an XML syntax error due to the </b> tag not being opened.

<?xml version='1.0' encoding='UTF-8' standalone='yes'?>   HTML text will follow
<html>
  <head>
    <title>Similarly, the 'script' tag will switch to the JavaScript parser:</title>
    <script type="text/javascript">
       // Press enter inside the object and your new line will be suitably
       // indented.
       var keyBindings = {
         enter: "newline-and-indent",
         tab: "reindent-selection",
         ctrl_enter: "reparse-buffer",
         ctrl_z: "undo",
         ctrl_y: "redo",
         ctrl_backspace: "undo-for-safari-which-stupidly-enough-blocks-ctrl-z"
       };

       // Press tab on the next line and the wrong indentation will be fixed.
             var regex = /foo|bar/i;

       function example(x) {
         // Local variables get a different colour than global ones.
         var y = 44.4;
         return x + y - z;
       }
    </script>
    <style>
      /* Some example CSS */

      @import url("something.css");

      body {
        margin: 0;
        padding: 3em 6em;

  and observing how the highlight changes.
