What are some best practices for handling conditional statements in PHP to avoid confusion and improve code readability?

When working with conditional statements in PHP, it is important to use clear and concise syntax to avoid confusion and improve code readability. One best practice is to use parentheses to clearly define the conditions being evaluated. Additionally, using proper indentation and spacing can make the code easier to follow.

// Example of using clear syntax and proper formatting for conditional statements
if ($condition1 && ($condition2 || $condition3)) {
    // Code block to execute if conditions are met
} elseif ($condition4) {
    // Code block to execute if condition4 is met
} else {
    // Code block to execute if none of the conditions are met
}
