In the context of PHP form handling, what are best practices for displaying error messages next to form fields and preventing layout shifts?

When displaying error messages next to form fields in PHP, it is best practice to use inline error messages to prevent layout shifts. One way to achieve this is by setting up a conditional statement that checks for errors and displays them inline next to the corresponding form fields using CSS. 

<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
  <label for="email">Email:</label>
  <input type="text" id="email" name="email">
  <?php if(isset($errors['email'])) { ?>
    <span class="error"><?php echo $errors['email']; ?></span>
  <?php } ?>
  
  <label for="password">Password:</label>
  <input type="password" id="password" name="password">
  <?php if(isset($errors['password'])) { ?>
    <span class="error"><?php echo $errors['password']; ?></span>
  <?php } ?>
  
  <input type="submit" value="Submit">
</form>
