How to replace placeholders with actual values?

Question

I need a function that replace every variable_name inside \'{}\' with the correct variable. Something like this:

$data[\"name\"] = \"Johnny\";
$data[\"age\"

You can try out vsprintf it has slightly different syntax

$string = 'hello my name is %s and I am %d years old';

$params = array('John', 29);

var_dump(vsprintf($string, $params));
//string(43) "hello my name is John and I am 29 years old"
