What best practices should be followed to ensure consistent character encoding and data submission in PHP scripts?

To ensure consistent character encoding and data submission in PHP scripts, it is important to set the appropriate character encoding in both the HTML form and the PHP script itself. This can be done by setting the 'charset' attribute in the HTML form and using functions like mb_internal_encoding() and mb_http_output() in the PHP script. Additionally, sanitizing user input using functions like htmlspecialchars() can help prevent data submission issues related to character encoding. 

// Set character encoding in HTML form
<form accept-charset="UTF-8">
  <!-- form fields -->
</form>

// Set character encoding in PHP script
<?php
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');

// Sanitize user input
$user_input = htmlspecialchars($_POST['user_input']);
?>
