What best practices can be followed to ensure consistent execution of PHP code across different pages or sections of a website?

To ensure consistent execution of PHP code across different pages or sections of a website, it is important to follow best practices such as creating reusable functions, organizing code into separate files, using include or require statements, and implementing error handling techniques. 

// Example of creating a reusable function to ensure consistent execution of code

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

// Example of including a file with common functions in multiple pages

// common_functions.php
function sanitizeInput($input) {
    // sanitize input here
    return $sanitizedInput;
}

// page1.php
include 'common_functions.php';
$sanitizedInput = sanitizeInput($_POST['input']);

// page2.php
include 'common_functions.php';
$sanitizedInput = sanitizeInput($_GET['input']);
