How can PHP beginners effectively handle complex logic and decision-making processes in their scripts?

Beginners can effectively handle complex logic and decision-making processes in their PHP scripts by breaking down the problem into smaller, manageable steps and using conditional statements like if, else if, and else to guide the flow of the script. It's also helpful to use functions and loops to organize and streamline the code.

// Example of using conditional statements to handle complex logic
$number = 10;

if ($number < 5) {
    echo "Number is less than 5";
} elseif ($number >= 5 && $number <= 10) {
    echo "Number is between 5 and 10";
} else {
    echo "Number is greater than 10";
}
