How can PHP arrays be effectively used to handle form data and input for data manipulation?

PHP arrays can be effectively used to handle form data by storing form input values as key-value pairs. This allows for easy access and manipulation of the data. To handle form data using PHP arrays, you can use the $_POST superglobal array to retrieve form input values and store them in an associative array for further processing. 

// Retrieve form input values using $_POST superglobal
$input_data = $_POST;

// Initialize an empty array to store form data
$form_data = [];

// Store form input values in the form_data array
foreach ($input_data as $key => $value) {
    $form_data[$key] = $value;
}

// Access and manipulate form data as needed
foreach ($form_data as $key => $value) {
    // Perform data manipulation or validation
    echo "Key: $key, Value: $value <br>";
}
