What are some alternative approaches to solving the issue of using variable names in strings in PHP?

Issue: When using variable names in strings in PHP, it can be cumbersome to concatenate variables with strings using the dot operator. An alternative approach is to use double quotes around the string and directly insert the variable within the string using curly braces. Example fix: 

$name = "John";
$age = 30;

// Using concatenation
$message = "Hello, " . $name . ". You are " . $age . " years old.";

// Using double quotes and curly braces
$message = "Hello, {$name}. You are {$age} years old.";

echo $message;
