How can PHP developers minimize the risk of link manipulation when passing parameters?

To minimize the risk of link manipulation when passing parameters in PHP, developers can use input validation and sanitization techniques. This involves checking and cleaning user input before using it in the application to prevent malicious code injection or manipulation. 

// Example of input validation and sanitization in PHP
$user_input = $_GET['user_input']; // Assuming user_input is a parameter passed in the URL

// Validate and sanitize the input
$clean_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Use the sanitized input in the application
echo "User input: " . $clean_input;
