Custom php function for replacing variable with value in PHP

How to write custom php function for replacing variable with value by passing function parameters?

$template = "Hello, {{name}}!";

$data = [
    'name'=> 'world'
];

echo replace($template, $data);

function replace($template, $data) {

    $name = $data['name'];
    
    return $template;
    
}

echo replace($template, $data); must return "Hello, world!"
Thank You!

>Solution :

One way would be to use the built-in str_replace function, like this:

foreach($data as $key => $value) {
  $template = str_replace("{{$key}}", $value, $template);
}

return $template;

This loops your data-array and replaces the keys with your values. Another approach would be RegEx
