What are some strategies for improving error handling and user feedback in PHP form submissions to enhance user experience?

Issue: Improving error handling and user feedback in PHP form submissions can enhance the user experience by providing clear and informative messages when errors occur. This can help users understand what went wrong and how to correct it, leading to a smoother form submission process. Code snippet: 

<?php
// Check if the form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Validate form data
    $name = $_POST["name"];
    if (empty($name)) {
        $error = "Name is required";
    }

    // If there are no errors, process the form data
    if (empty($error)) {
        // Process form data here
        echo "Form submitted successfully!";
    } else {
        // Display error message to the user
        echo $error;
    }
}
?>

<form method="post" action="">
    <input type="text" name="name" placeholder="Name">
    <button type="submit">Submit</button>
</form>
