What are the common pitfalls when integrating PHP scripts with client-side interactions using HTML buttons and JavaScript functions?

Common pitfalls when integrating PHP scripts with client-side interactions using HTML buttons and JavaScript functions include not properly handling form submissions, not sanitizing user input, and not securely passing data between the client and server. To solve these issues, make sure to use POST method for form submissions, sanitize user input to prevent SQL injection and cross-site scripting attacks, and use encryption or secure communication protocols when passing sensitive data between the client and server. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Sanitize user input
    $input = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);

    // Perform necessary PHP operations with sanitized input
    // For example, updating database records
}
?>
