Are there any best practices for managing placeholders in PHP templates to avoid unexpected replacements?

When managing placeholders in PHP templates, it's important to use unique and specific placeholder names to avoid unexpected replacements. One best practice is to prefix placeholders with a unique identifier to make them distinct. Additionally, consider using a templating engine that provides built-in functionality for managing placeholders to prevent any conflicts. 

// Example of using unique identifiers for placeholders
$template = "Hello {NAME}, welcome to {SITE_NAME}!";
$replacements = [
    '{NAME}' => 'John',
    '{SITE_NAME}' => 'My Website'
];

foreach ($replacements as $placeholder => $value) {
    $template = str_replace($placeholder, $value, $template);
}

echo $template;
