How can JavaScript be utilized to asynchronously submit a form and change the location of the current page in PHP web development?

To asynchronously submit a form and change the location of the current page in PHP web development, you can use JavaScript to make an AJAX request to a PHP script that processes the form data and returns a response. Once the response is received, you can use JavaScript to redirect the user to a new page based on the result. 

<?php
// PHP script to process form data
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    
    // Return a response
    $response = "Form submitted successfully!";
    echo json_encode($response);
    exit;
}
?>
```

```javascript
// JavaScript code to asynchronously submit form and redirect
document.getElementById("myForm").addEventListener("submit", function(event) {
    event.preventDefault();
    
    var formData = new FormData(this);
    
    fetch("process_form.php", {
        method: "POST",
        body: formData
    })
    .then(response => response.json())
    .then(data => {
        alert(data); // Display response message
        window.location.href = "new_page.php"; // Redirect to new page
    })
    .catch(error => console.error("Error:", error));
});
