What are some best practices for separating PHP and JavaScript code to avoid errors?

To avoid errors when mixing PHP and JavaScript code, it's best practice to separate them into distinct files or sections. This separation helps maintain clean and organized code, reduces the chances of syntax errors, and improves readability. By keeping PHP code in separate files and JavaScript code in separate script tags within HTML files, you can easily troubleshoot and debug any issues that may arise. 

// Separate PHP code into a separate file
include 'functions.php';

// HTML code with JavaScript in a separate script tag
<!DOCTYPE html>
<html>
<head>
    <title>Separating PHP and JavaScript</title>
</head>
<body>
    <h1>Welcome!</h1>
    <button onclick="myFunction()">Click me</button>
    
    <script>
        function myFunction() {
            alert('Hello, world!');
        }
    </script>
</body>
</html>
