How can browser compatibility affect PHP form functionality?

Browser compatibility can affect PHP form functionality if certain HTML elements or attributes are not supported by all browsers. To ensure compatibility, it is important to use standard HTML elements and attributes that are widely supported. Additionally, using CSS for styling instead of relying on browser-specific attributes can help ensure consistent functionality across different browsers. 

<form action="submit.php" method="post">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name">
  <input type="submit" value="Submit">
</form>
