What is the correct syntax for concatenating variables and strings in PHP?

When concatenating variables and strings in PHP, you can use the dot (.) operator to combine them together. This allows you to create dynamic strings by including variable values within a larger string. Make sure to enclose variables within curly braces {} to clearly separate them from the surrounding text. 

// Concatenating variables and strings in PHP
$name = "John";
$age = 25;

// Using the dot operator to concatenate variables and strings
echo "Hello, " . $name . "! You are " . $age . " years old.";
