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\"         


        

Answer 1

Here you go:

$data["name"] = "Johnny";
$data["age"] = "20";

$string = "Hello my name is {name} and I'm {age} years old.";

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

echo $string;
