How can the use of arrays in PHP echo or print statements impact the output and processing of form data?

Using arrays in PHP echo or print statements can lead to unexpected output and processing of form data, as arrays are not directly printable. To properly display array data, you should loop through the array and print each element individually. This ensures that the data is displayed in a readable format. 

<?php
// Example form data stored in an array
$formData = [
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'phone' => '123-456-7890'
];

// Loop through the array and print each key-value pair
foreach ($formData as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}
?>
