In PHP development, what role does browser compatibility play in ensuring proper form validation and submission functionality?

Browser compatibility is crucial in ensuring proper form validation and submission functionality in PHP development because different browsers may interpret HTML and JavaScript code differently. To ensure a consistent user experience across various browsers, developers need to test their forms on multiple browsers to ensure they function correctly. Using a JavaScript library like jQuery can help simplify form validation and submission, as it provides a consistent API for interacting with form elements. 

<form action="submit.php" method="post">
  <input type="text" name="username" id="username" required>
  <input type="password" name="password" id="password" required>
  <button type="submit">Submit</button>
</form>
