What best practices should be followed when handling conditional statements in PHP code?

When handling conditional statements in PHP code, it is important to follow best practices to ensure readability and maintainability. This includes using clear and descriptive variable names, properly indenting code blocks, and avoiding nested conditional statements when possible. Additionally, it is recommended to use braces {} even for single-line if statements to avoid potential bugs and improve code consistency.
