How can string concatenation be used effectively in PHP to generate dynamic code?

String concatenation can be used effectively in PHP to generate dynamic code by combining static text with variables or expressions. This allows for the creation of customized output based on the values of variables or conditions within the code. By using the concatenation operator (.), developers can build complex strings dynamically, making the code more flexible and adaptable to different scenarios. 

// Example of using string concatenation to generate dynamic code
$name = "John";
$age = 25;

// Concatenating variables with static text to generate a personalized message
$message = "Hello, my name is " . $name . " and I am " . $age . " years old.";

echo $message;
