What best practices should be followed when using if-elseif-else statements in PHP?

When using if-elseif-else statements in PHP, it is important to follow best practices to ensure readability and maintainability of your code. One best practice is to use elseif instead of else if to prevent confusion and potential errors. Another best practice is to use indentation and proper formatting to make the code more readable. Additionally, it is recommended to use switch statements instead of long chains of if-elseif-else statements for better performance and clarity. 

// Example of using if-elseif-else statements with best practices

$grade = 85;

if ($grade >= 90) {
    echo "A";
} elseif ($grade >= 80) {
    echo "B";
} elseif ($grade >= 70) {
    echo "C";
} else {
    echo "F";
}
