What best practices should be followed when structuring complex conditional statements in PHP?

When structuring complex conditional statements in PHP, it is important to follow best practices to ensure readability and maintainability of the code. One common approach is to use nested if-else statements or switch-case statements to handle multiple conditions. Additionally, using logical operators such as && (AND) and || (OR) can help simplify complex conditions.

// Example of structuring complex conditional statements in PHP
if ($condition1 && $condition2) {
    // Code block to execute if both conditions are true
} elseif ($condition3 || $condition4) {
    // Code block to execute if either condition3 or condition4 is true
} else {
    // Code block to execute if none of the conditions are met
}
