Why is it important to understand the difference between PHP functions and language constructs, such as include, when writing code?

It is important to understand the difference between PHP functions and language constructs like include because they serve different purposes and have different syntax rules. Functions are reusable blocks of code that perform a specific task, while language constructs are built-in features of PHP that do not follow the same syntax rules as functions. Knowing the distinction between the two can help prevent errors and confusion when writing code. 

// Example of using include as a language construct
include 'header.php';

// Example of using a function
function addNumbers($num1, $num2) {
    return $num1 + $num2;
}
$total = addNumbers(5, 10);
echo $total;
