How can multiple cities be selected and displayed with their corresponding dates when the user clicks on a submit button in a PHP form?

To achieve this, you can use an HTML form with checkboxes for selecting multiple cities and a submit button. When the user clicks on the submit button, the form data is sent to a PHP script. In the PHP script, you can use a loop to iterate through the selected cities and display their corresponding dates. 

<form method="post" action="display_cities.php">
    <input type="checkbox" name="cities[]" value="New York"> New York<br>
    <input type="checkbox" name="cities[]" value="Los Angeles"> Los Angeles<br>
    <input type="checkbox" name="cities[]" value="Chicago"> Chicago<br>
    <input type="submit" value="Submit">
</form>
```

In the `display_cities.php` script:

```php
<?php
if(isset($_POST['cities'])) {
    $selectedCities = $_POST['cities'];
    
    foreach($selectedCities as $city) {
        // Get and display the corresponding date for each city
        switch($city) {
            case 'New York':
                echo 'New York: January 1, 2022<br>';
                break;
            case 'Los Angeles':
                echo 'Los Angeles: February 15, 2022<br>';
                break;
            case 'Chicago':
                echo 'Chicago: March 30, 2022<br>';
                break;
        }
    }
}
?>
