Are there any potential pitfalls when using variables and constants together in PHP strings?

When using variables and constants together in PHP strings, one potential pitfall is forgetting to properly concatenate the variables and constants with the string. To solve this issue, make sure to use the concatenation operator (.) to combine the variables/constants with the string. 

// Example of using variables and constants in PHP strings
$name = "John";
define("AGE", 30);

// Concatenate variables and constants with the string using the '.' operator
echo "My name is " . $name . " and I am " . AGE . " years old.";
