How can arrays and loops be utilized in PHP to streamline form processing and output generation?

When processing form data in PHP, arrays can be used to efficiently store and manipulate input values. By using loops, such as foreach loops, we can iterate over arrays to generate dynamic output based on the form data. This approach streamlines the processing of form submissions and simplifies the generation of HTML output. 

// Sample PHP code snippet demonstrating the use of arrays and loops for form processing and output generation

// Assume form data is submitted via POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Initialize an empty array to store form input values
    $formData = [];

    // Iterate over the POST data to populate the $formData array
    foreach ($_POST as $key => $value) {
        $formData[$key] = $value;
    }

    // Generate output based on the form data using a foreach loop
    echo "<ul>";
    foreach ($formData as $key => $value) {
        echo "<li>$key: $value</li>";
    }
    echo "</ul>";
}
