What are common pitfalls when using if statements in PHP scripts?

Common pitfalls when using if statements in PHP scripts include forgetting to use double equals (==) for comparison instead of a single equals sign (=), not properly nesting if statements, and not considering all possible conditions. To avoid these pitfalls, always double-check your comparison operators, ensure proper nesting of if statements, and consider all possible scenarios when writing your conditions. Example PHP code snippet: 

// Example of properly using if statements with correct comparison operators and nesting

$age = 25;

if ($age == 18) {
    echo "You are 18 years old.";
} elseif ($age > 18) {
    echo "You are older than 18 years old.";
} else {
    echo "You are younger than 18 years old.";
}
