How can beginners improve their understanding of PHP functions and their return values for better code execution?
Beginners can improve their understanding of PHP functions and their return values by practicing writing functions with different return types and using them in their code. They can also refer to the PHP documentation to learn about built-in functions and their return values. Additionally, debugging their code and using var_dump() or print_r() functions to inspect the return values can help in understanding how functions are working.
// Example code snippet demonstrating the use of functions and return values
function addNumbers($num1, $num2) {
return $num1 + $num2;
}
$result = addNumbers(5, 3);
echo $result; // Output: 8
