How can PHP developers efficiently handle repetitive code segments in their projects?

PHP developers can efficiently handle repetitive code segments in their projects by creating reusable functions or classes. By encapsulating common functionality into functions or classes, developers can easily call these components whenever needed, reducing code duplication and improving maintainability. 

// Example of creating a reusable function to handle repetitive code segments
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

// Example of using the reusable function
$total = calculateTotal(10, 5);
echo "Total: $" . $total;
