How can one effectively replace variables in a template using PHP?

To effectively replace variables in a template using PHP, you can use the str_replace function to search for specific placeholders in the template and replace them with the corresponding values. By defining placeholders in the template and replacing them with actual values dynamically, you can create a dynamic and customizable template system.

$template = "Hello, [name]! Your email is [email].";
$name = "John Doe";
$email = "johndoe@example.com";

$template = str_replace("[name]", $name, $template);
$template = str_replace("[email]", $email, $template);

echo $template;
