In what ways can planning with flowcharts and diagrams improve the structure and efficiency of PHP scripts?

Planning with flowcharts and diagrams can improve the structure and efficiency of PHP scripts by providing a visual representation of the code logic, helping developers identify potential bottlenecks or inefficiencies, and allowing for better organization of functions and processes. This can lead to more streamlined and optimized code that is easier to maintain and debug.

// Example of using flowcharts and diagrams to improve PHP script structure and efficiency

// Step 1: Plan out the logic of the script using a flowchart or diagram
// Step 2: Break down the code into smaller, more manageable functions based on the flowchart
// Step 3: Use the diagram as a reference to ensure the code follows the planned logic

// Example code snippet implementing the above steps

function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

$price = 10;
$quantity = 5;

$total = calculateTotal($price, $quantity);

echo "Total: " . $total;
