In PHP, how does context switching prevent certain types of user input manipulation?

Context switching in PHP helps prevent certain types of user input manipulation by ensuring that the input data is properly sanitized and validated before being used in different contexts. This helps to prevent common security vulnerabilities such as SQL injection, cross-site scripting (XSS), and other types of attacks that rely on manipulating user input. 

// Example of using context switching to prevent user input manipulation
$input = $_POST['user_input'];

// Sanitize and validate the input data before using it in different contexts
$clean_input = filter_var($input, FILTER_SANITIZE_STRING);

// Use the sanitized input data in different contexts
echo "User input: " . $clean_input;
// Continue with the rest of your PHP code
