What are the similarities and differences between pseudocode, program flowcharts, and structure diagrams in PHP programming?

Pseudocode, program flowcharts, and structure diagrams are all tools used in software development to plan and visualize the logic of a program before writing actual code. Pseudocode is a high-level description of the algorithm in plain English or another natural language, making it easy to understand for both developers and non-developers. Program flowcharts use graphical symbols to represent the steps in a program, showing the flow of control between different parts of the program. Structure diagrams, on the other hand, provide a more detailed view of the program's structure, including functions, classes, and their relationships. 

// Example PHP code snippet
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}
$total = calculateTotal(10, 5);
echo "Total: " . $total;
