How can the structure of PHP code affect the functionality of if-else statements?

The structure of PHP code can affect the functionality of if-else statements by causing syntax errors or logical errors if not properly organized. To ensure the if-else statements work correctly, it is important to pay attention to the placement of curly braces, indentation, and the use of proper syntax.

// Correct structure of if-else statements
if ($condition) {
    // Code block for if statement
} else {
    // Code block for else statement
}
