What best practices should be followed when handling form submission with TinyMCE in PHP?

When handling form submissions with TinyMCE in PHP, it is important to properly sanitize and validate the input data to prevent security vulnerabilities such as cross-site scripting (XSS) attacks. One common best practice is to use the htmlspecialchars() function to escape any HTML characters in the input before saving it to the database. Additionally, it is recommended to set a maximum length for the input to prevent potential abuse. 

// Sanitize and validate form submission with TinyMCE in PHP
$content = isset($_POST['content']) ? htmlspecialchars($_POST['content']) : '';

// Validate content length
if(strlen($content) > 1000) {
    echo "Content exceeds maximum length of 1000 characters";
} else {
    // Save content to database or perform other actions
}
