+## patTemplate
+
+> [patTemplate](https://github.com/wernerwa/pat-template) non-compiling PHP templating engine, that uses XML tags to divide a document into different parts
+
+```xml
+<patTemplate:tmpl name="page">
+  This is the main page.
+  <patTemplate:tmpl name="foo">
+    It contains another template.
+  </patTemplate:tmpl>
+  <patTemplate:tmpl name="hello">
+    Hello {NAME}.<br/>
+  </patTemplate:tmpl>
+</patTemplate:tmpl>
+```
+
+---
+
+## PHPlib and HTML_Template_PHPLIB
+
+[HTML_Template_PHPLIB](https://github.com/pear/HTML_Template_PHPLIB) is the same as PHPlib but ported to Pear.
+
+`authors.tpl`
+
+```html
+<html>
+ <head><title>{PAGE_TITLE}</title></head>
+ <body>
+  <table>
+   <caption>Authors</caption>
+   <thead>
+    <tr><th>Name</th><th>Email</th></tr>
+   </thead>
+   <tfoot>
+    <tr><td colspan="2">{NUM_AUTHORS}</td></tr>
+   </tfoot>
+   <tbody>
+<!-- BEGIN authorline -->
+    <tr><td>{AUTHOR_NAME}</td><td>{AUTHOR_EMAIL}</td></tr>
+<!-- END authorline -->
+   </tbody>
+  </table>
+ </body>
+</html>
+```
+
+`authors.php`
+
+```php
+<?php
+//we want to display this author list
+$authors = array(
+    'Christian Weiske'  => 'cweiske@php.net',
+    'Bjoern Schotte'     => 'schotte@mayflower.de'
+);
+
+require_once 'HTML/Template/PHPLIB.php';
+//create template object
+$t =& new HTML_Template_PHPLIB(dirname(__FILE__), 'keep');
+//load file
+$t->setFile('authors', 'authors.tpl');
+//set block
+$t->setBlock('authors', 'authorline', 'authorline_ref');
+
+//set some variables
+$t->setVar('NUM_AUTHORS', count($authors));
+$t->setVar('PAGE_TITLE', 'Code authors as of ' . date('Y-m-d'));
+
+//display the authors
+foreach ($authors as $name => $email) {
+    $t->setVar('AUTHOR_NAME', $name);
+    $t->setVar('AUTHOR_EMAIL', $email);
+    $t->parse('authorline_ref', 'authorline', true);
+}
+
+//finish and echo
+echo $t->finish($t->parse('OUT', 'authors'));
+?>
+```
+
+---
+
+## Plates
+
+Plates is inspired by Twig but a native PHP template engine instead of a compiled template engine.
+
+controller:
+
+```php
+// Create new Plates instance
+$templates = new League\Plates\Engine('/path/to/templates');
+
+// Render a template
+echo $templates->render('profile', ['name' => 'Jonathan']);
+```
+
+page template:
+
+```php
+<?php $this->layout('template', ['title' => 'User Profile']) ?>
+
+<h1>User Profile</h1>
+<p>Hello, <?=$this->e($name)?></p>
+```
+
+layout template:
+
+```php
+<html>
+  <head>
+    <title><?=$this->e($title)?></title>
+  </head>
+  <body>
+    <?=$this->section('content')?>
+  </body>
+</html>
+```
