Join For FreeSmarty. v3.0.6
It’s probably the most famous template engine. It’s a mature project.
For years it was “the” template engine and the others were the
“alternatives”. It was famous because of the speed.
Twig. v1.0.0-RC1-8
It’s a new template engine developed by Fabien Potencier, the creator of the symfony framework. One of the PHP’s rock stars nowadays. It’s going to be an important part of the new symfony 2.0 framework. Twig borrows the template syntax from Django (probably the main web framework if we work with Python)
Haanga. v1.0.4-14
It’s another new template engine using the Django style. It was developed for Menéame by César Rodas.
I’ve decided to create two tests. One with a simple template and another using template Inheritance. The both cases renders one html page using one variable, filters and for loop to create an HTML table. Basically I’ve created those test because they’re the things I normally use. I will run the test with an HTML table of 50 rows and 1000 rows.
Simple template
Smarty
{* Smarty. indexFull.tpl*}
<html>
<head>
<title>{$title}</title>
</head>
<body>
<h2>An example with {$title|capitalize}</h2>
<b>Table with {$number|escape} rows</b>
<table>
{foreach $table as $row}
<tr bgcolor="{cycle values="#aaaaaa,#ffffff"}">
<td>{$row.id}</td>
<td>{$row.name}</td>
</tr>
{foreachelse}
<tr><td>No items were found</td></tr>
{/foreach}
</table>
</body>
</html>And the PHP code:
// index.php
$time = microtime(TRUE);
$mem = memory_get_usage();
define('BASE_DIR', dirname(__file__));
require(BASE_DIR . '/include/smarty/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir(BASE_DIR . '/smarty/templates');
$smarty->setCompileDir(BASE_DIR . '/smarty/templates_c');
$smarty->setCacheDir(BASE_DIR . '/smarty/cache');
$smarty->setConfigDir(BASE_DIR .'/smarty/configs');
$smarty->assign('title', "smarty");
$rows = 1000;
$data = array();
for ($i=0; $i<$rows; $i++ ) {
$data[] = array('id' => $i, 'name' => "name {$i}");
}
$smarty->assign('table', $data);
$smarty->assign('number', $rows);
$smarty->display('indexFull.tpl');
print_r(array('memory' => (memory_get_usage() - $mem) / (1024 * 1024), 'seconds' => microtime(TRUE) - $time));
Twig
{# Twig. indexFull.html #}
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<h2>An example with {{ title|title }}</h2>
<b>Table with {{ number|escape}} rows</b>
<table>
{% for row in table %}
<tr bgcolor="{{ cycle(['#aaaaaa', '#ffffff'], row.id) }}">
<td>{{ row.id }}</td>
<td>{{ row.name }}</td>
</tr>
{% endfor %}
</table>
</body>
</html>
And the PHP code:// index.php
$time = microtime(TRUE);
$mem = memory_get_usage();
define('BASE_DIR', dirname(__file__));
require_once BASE_DIR . '/include/Twig/Autoloader.php';
Twig_Autoloader::register();
$loader = new Twig_Loader_Filesystem(BASE_DIR . '/twig/templates');
$twig = new Twig_Environment($loader, array(
'cache' => BASE_DIR . '/twig/compiled',
'auto_reload' => true
));
$template = $twig->loadTemplate('indexFull.html');
$rows = 1000;
$data = array();
for ($i = 0; $i < $rows; $i++) {
$data[] = array('id' => $i, 'name' => "name {$i}");
}
$template->display(array(
'number' => $rows,
'title' => 'twig',
'table' => $data
));
print_r(array('memory' => (memory_get_usage() - $mem) / (1024 * 1024), 'seconds' => microtime(TRUE) - $time));
Haanga
{# Haanga. indexFull.html #}
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<h2>An example with {{ title|title }}</h2>
<b>Table with {{ number|escape}} rows</b>
<table>
{% for row in table %}
<tr bgcolor="{% cycle '#aaaaaa' '#ffffff' %}">
<td>{{ row.id }}</td>
<td>{{ row.name }}</td>
</tr>
{% endfor %}
</table>
</body>
</html>
And the PHP code:
// index.php
$time = microtime(TRUE);
$mem = memory_get_usage();
define('BASE_DIR', dirname(__file__));
require(BASE_DIR . '/include/Haanga.php');
Haanga::configure(array(
'template_dir' => BASE_DIR . '/haanga/templates',
'cache_dir' => BASE_DIR . '/haanga/compiled',
));
$rows = 1000;
$data = array();
for ($i=0; $i<$rows; $i++ ) {
$data[] = array('id' => $i, 'name' => "name {$i}");
}
Haanga::Load('indexFull.html', array(
'number' => $rows,
'title' => 'haanga',
'table' => $data
));
print_r(array('memory' => (memory_get_usage() - $mem) / (1024 * 1024), 'seconds' => microtime(TRUE) - $time));
With template Inheritance
With this test I use the same php file, changing template name from indexFull to index.
Smarty
{* Smarty. index.tpl*}
{extends file="layout.tpl"}
{block name=table}
<table>
{foreach $table as $row}
<tr bgcolor="{cycle values="#aaaaaa,#ffffff"}">
<td>{$row.id}</td>
<td>{$row.name}</td>
</tr>
{foreachelse}
<tr><td>No items were found</td></tr>
{/foreach}
</table>
{/block}
{* Smarty. layout.tpl*}
<html>
<head>
<title>{$title}</title>
</head>
<body>
<h2>An example with {$title|capitalize}</h2>
<b>Table with {$number|escape} rows</b>
{block name=table}{/block}
</body>
</html>
Twig
{# Twig. index.html #}
{% extends "layout.html" %}
{% block table %}
<table>
{% for row in table %}
<tr bgcolor="{{ cycle(['#aaaaaa', '#ffffff'], row.id) }}">
<td>{{ row.id }}</td>
<td>{{ row.name }}</td>
</tr>
{% else %}
<tr><td>No items were found</td></tr>
{% endfor %}
</table>
{% endblock %}
{# Twig. layout.html #}
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<h2>An example with {{ title|title }}</h2>
<b>Table with {{ number|escape}} rows</b>
{% block table %}{% endblock %}
</body>
</html>
Haanga
{% extends "layout.html" %}
{# Haanga. index.html #}
{% block table %}
<table>
{% for row in table %}
<tr bgcolor="{% cycle '#aaaaaa' '#ffffff' %}">
<td>{{ row.id }}</td>
<td>{{ row.name }}</td>
</tr>
{% endfor %}
</table>
{% endblock %}
{# Haanga. layout.html #}
<html>
<head>
<title>{{ title }}</title>
</head>
<body>
<h2>An example with {{ title|title }}</h2>
<b>Table with {{ number|escape}} rows</b>
{% block table %}{% endblock %}
</body>
</html>

Haanga really rocks in the test. It’s the fastest in all cases and it’s the best using memory. The main problem I’ve seen with Haanga is the lack of documentation. When I wanted to use the cycle filter (to create the zebra style in the HTML table) I didn’t find anything about it. I had to browse the source code and finally I found it in one tests. Whereas Smarty documentation is brilliant and Twig is good enough.
The HTML template syntax is almost the same with Twig and Haanga (in fact both of them are Django style). Smarty is a bit different but is very similar. The PHP part in Smarty looks like a bit old fashioned compared with Haanga and Twig, but it’s really easy to use.
The performance of Twig and Smarty are similar. Twig is slightly better. But with simple templates i’ts almost the same.
