How can user input be processed and displayed in a PHP form using arrays?

When processing user input in a PHP form using arrays, you can use the $_POST superglobal array to retrieve the input values submitted by the user. You can then store these values in an array and display them accordingly. To display the input values, you can use a loop to iterate through the array and output each value. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $input_values = $_POST['input_values'];
    
    // Display the input values
    foreach ($input_values as $value) {
        echo $value . "<br>";
    }
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="text" name="input_values[]">
    <input type="text" name="input_values[]">
    <input type="text" name="input_values[]">
    <input type="submit" value="Submit">
</form>
