What are some common pitfalls when using jQuery and PHP together in a web development project?

One common pitfall when using jQuery and PHP together is not properly sanitizing user input before processing it on the server side. This can lead to security vulnerabilities such as SQL injection or cross-site scripting attacks. To solve this issue, always validate and sanitize user input before using it in your PHP code. 

// Example of sanitizing user input in PHP
$user_input = $_POST['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);
