How to modify the homepage style in php template

When developing a website, templates are a very important component. Using templates can simplify the website development process and improve development efficiency. For PHP developers, using the PHP template engine is also a very common development method.

When using the PHP template engine, we can easily modify the website style, such as the homepage style, to meet the needs of the website. In this article, I will introduce how to use the PHP template engine (Smarty) to modify the website homepage style.

1. Installing Smarty

Before we start modifying the website style, we first need to install and configure the Smarty template engine. First, we can download the latest Smarty template engine from the official website. Once unzipped, we can place the Smarty directory into our website directory. Next, we need to introduce the Smarty class into the PHP file of the website.

require_once('Smarty.class.php');
$smarty = new Smarty();

Now, we have successfully introduced Smarty into our website. Next, we need to set some configuration parameters of Smarty, such as Smarty's cache directory, compilation directory, etc. These parameters can be set in the configuration file or in the PHP file. Below is a simple PHP file used to set Smarty's configuration parameters.

require_once('Smarty.class.php');
$smarty = new Smarty();

$smarty->setTemplateDir('./templates/');
$smarty->setCompileDir('./templates_c/');
$smarty->setCacheDir('./cache/');

2. Modify the homepage style

Now that we have successfully set the configuration parameters of Smarty, we can start to modify the homepage style. We can modify the website style by modifying the template file. Template files typically include HTML, CSS, and JavaScript code and some Smarty markup.

The following is a simple template file used to display the website homepage:

nbsp;html>


    <meta>
    <title>{$title}</title>
    <link>


    <div>
        <h1 id="title">{$title}</h1>
    </div>
    <div>
        {$content}
    </div>

The above code is a typical HTML code, in which we use some Smarty tags, such as {$title} and { $content} to set these values ​​dynamically in the PHP file. Next, we can modify the style of the website homepage by modifying the CSS file.

The following is a simple CSS file for modifying the style of the website homepage:

body {
    font-family: Arial, Helvetica, sans-serif;
    margin: 0;
    padding: 0;
}

#header {
    background-color: #333;
    color: #fff;
    min-height: 50px;
    padding: 10px;
}

#header h1 {
    margin: 0;
}

#content {
    margin: 10px;
    padding: 10px;
    background-color: #f0f0f0;
}

The above code defines three CSS classes, which are used to set the font, background color, etc. of the entire website. Style, and set the style of the title and main content of the website homepage. Next, we can set these styles dynamically in the PHP file.

3. Set the style

Now that we have a simple template file and a CSS file, we can dynamically set the homepage style in the PHP file. We can set the variable values ​​used in the template through Smarty's assign method.

require_once('Smarty.class.php');
$smarty = new Smarty();

$smarty->setTemplateDir('./templates/');
$smarty->setCompileDir('./templates_c/');
$smarty->setCacheDir('./cache/');

$smarty->assign('title', '我的网站');
$smarty->assign('content', '欢迎来到我的网站！这是我的主页。');
$smarty->display('index.tpl');

The above PHP code sets two Smarty variables, which are used to set the title and main content of the website homepage. Finally, we render the template through the display method and view the effect in the browser.

4. Summary

In this article, we introduced how to use the PHP template engine (Smarty) to modify the website homepage style. First, we installed and configured the Smarty template engine. Then, we define the style of the website homepage through template files and CSS files. Finally, we dynamically styled the homepage through a PHP file and viewed the effect in the browser.
