About

ZeusTemplateEngine is a template engine which implements the UniversalTemplateEngine interface.

This template engine uses the most flexible template language ever: php.

The template files are regular php files.

Inside template files, the following variables are available:

• $z: an array containing all the variables passed to the template

How to use?

• First create a template file. I will use /path/to/my_app/pages/zeus/home.php. Put the following content in it.

<h1>The home page</h1>
<p>
    Hello, this is an example template for Zeus.
    In a Zeus template, we write the variables using the most flexible template language ever: php.
    For instance, the following fruit is actually a variable, look how it's done in the source code:
</p>
<ul>
    <li>fruit: <?php echo $z['fruit']; ?></li>
</ul>

Now we want to render this template.

We have two options:

• either we call it by its file name directly
• or we use the directory alias provided by Zeus by default

Using the file name directly

We just need to call the renderByPath method, as shown in the following code:

$tpl = "/path/to/my_app/pages/zeus/home.php";
$o = new ZeusTemplateEngine();
echo $o->renderByPath($tpl, [
    "fruit" => "apple",
]);

Using the directory alias system

You first need to define directory aliases with the setDirectories method, then you can call the render method.

Then, in your main application file, paste the following code:

$o = new ZeusTemplateEngine();

$o->setDirectories([
    "pages" => "/path/to/my_app/pages", // define the pages alias
]);


// now render the template
$html = $o->render("pages:zeus/home.php", [
    "fruit" => "apple",
]);


if (false === $html) {
    a($o->getErrors());
} else {
    echo $html;
}

The resourceIdentifier (pages:zeus/home.php) has the following notation:

• <directoryAlias> <:> <templateRelativePath>

With:

• directoryAlias: one of the directory aliases defined with the setDirectories method
• templateRelativePath: the relative path from the given aliased directory to the template
