What are some best practices for implementing templatesystems in PHP without relying on PEAR?

When implementing template systems in PHP without relying on PEAR, it is important to separate the presentation logic from the business logic to maintain code readability and reusability. One approach is to use a simple templating engine like Smarty or Twig, which provide syntax for placeholders and logic-less templates. Another option is to create your own template system by defining placeholders in your HTML files and replacing them with dynamic content using PHP. 

// Example of implementing a simple template system in PHP without relying on PEAR

// Define a function to render a template file with dynamic data
function renderTemplate($template, $data) {
    ob_start();
    extract($data);
    include $template;
    return ob_get_clean();
}

// Define template file (e.g., template.php)
// <html>
// <head>
//     <title><?php echo $title; ?></title>
// </head>
// <body>
//     <h1><?php echo $heading; ?></h1>
//     <p><?php echo $content; ?></p>
// </body>
// </html>

// Define data to be passed to the template
$data = [
    'title' => 'Example Page',
    'heading' => 'Welcome to our website!',
    'content' => 'This is a sample content.'
];

// Render the template with dynamic data
echo renderTemplate('template.php', $data);
