What best practices should be followed when handling errors, separating PHP from HTML, and using JavaScript for redirection in PHP scripts?

When handling errors in PHP scripts, it is best practice to use try-catch blocks to catch exceptions and handle them gracefully. Separating PHP logic from HTML presentation ensures cleaner and more maintainable code. When using JavaScript for redirection in PHP scripts, it is recommended to use the header() function to send HTTP headers for the redirection. 

try {
    // PHP logic here
} catch (Exception $e) {
    // Handle errors gracefully
    echo "An error occurred: " . $e->getMessage();
}

// Separate PHP logic from HTML presentation
?>
<!DOCTYPE html>
<html>
<head>
    <title>Example Page</title>
</head>
<body>
    <h1>Welcome to my page</h1>
</body>
</html>

<?php
// Redirect using JavaScript
echo "<script>window.location = 'http://www.example.com';</script>";
