PHP is a scripting language widely used in web development. Many websites use PHP to dynamically generate web content. Installing templates is an important operation in PHP development. Next, this article will introduce you in detail how to install PHP templates.

1. Preparation

Before installing the template, we need to ensure that the following conditions are met:

1. PHP has been installed

To install the PHP template , PHP must be installed first. Make sure PHP is installed on your server and has a version number higher than 5.4.

2. Template engine installed

The template engine is a library that converts templates into executable PHP code. There are many PHP template engines on the market to choose from, such as Smarty, Twig, Blade, etc. In this article, we will introduce Smarty as an example.

3. The template to be installed is ready

Select the template you want to use and download it locally.

2. Install Smarty

1. Download the Smarty library

Download the Smarty library from the official website https://www.smarty.net/download. Unzip it to your server, for example /var/www/html/smarty.

2. Create Smarty configuration file

In the /var/www/html/smarty folder, create a file named config.php to store Smarty configuration information. The following is a sample configuration file:

<?php
define(&#39;SMARTY_DIR&#39;, &#39;/var/www/html/smarty/libs/&#39;);
require_once(SMARTY_DIR . &#39;Smarty.class.php&#39;);
$smarty = new Smarty();
$smarty->caching = false;
$smarty->template_dir = '/var/www/html/smarty/templates/';
$smarty->compile_dir = '/var/www/html/smarty/templates_c/';
$smarty->config_dir = '/var/www/html/smarty/configs/';
$smarty->cache_dir = '/var/www/html/smarty/cache/';
?>

Copy after login

In this configuration file, we set the Smarty compiled template directory to /var/www/html/smarty/templates_c/, and the Smarty configuration file directory is set to /var /www/html/smarty/configs/, Smarty’s cache directory is set to /var/www/html/smarty/cache/.

3. Create a Smarty template folder

In the /var/www/html/smarty folder, create a folder named templates to store template files.

4. Add template files in the template folder

Add the template files to be installed to the /var/www/html/smarty/templates/ folder.

5. Use Smarty syntax in template files

You can use the template syntax provided by Smarty in template files. For example:

<html>
<head>
<title>{$title}</title>
</head>
<body>
<h1>Welcome {$name}!</h1>
</body>
</html>

Copy after login

In this example, we use Smarty’s {$name} and {$title} variables as placeholders in the template.

6. Compile Smarty template files

In the project root directory, execute the following command to use Smarty to compile all template files:

php /var/www/html/smarty/libs/Smarty.class.php /var/www/html/smarty/templates/ /var/www/html/smarty/templates_c/

Copy after login

After execution, all Template files will be compiled into executable PHP code by Smarty and stored in the /var/www/html/smarty/templates_c/ folder.

3. Use Smarty rendering template

After installing Smarty, we need to use PHP code to call the Smarty rendering template. Here is an example:

<?php
require_once(&#39;/var/www/html/smarty/config.php&#39;);
$smarty->assign('title', 'Welcome to My Site');
$smarty->assign('name', 'John Doe');
$smarty->display('index.tpl');
?>

Copy after login

In this example, we load the Smarty configuration file and pass the variables $title and $name to the template. Finally, we call Smarty's display() function and specify the template file name to be rendered as index.tpl.

After execution, the placeholders {$title} and {$name} in the template file will be replaced with corresponding variable values to generate the final HTML code.

4. Summary

Through the above steps, we have learned how to install PHP templates and use Smarty to render templates. Of course, this is just a basic example. In fact, there are many advanced applications and techniques that we need to learn and apply in depth.
