How can escaping characters be used to prevent errors in PHP scripts when passing GET parameters?

Escaping characters can be used to prevent errors in PHP scripts when passing GET parameters by ensuring that any special characters within the parameter values are properly encoded. This helps to avoid issues such as injection attacks or syntax errors that may occur when handling user input. 

// Example of using PHP's built-in function urlencode() to escape characters in GET parameters

// Get the value of the 'name' parameter from the URL
$name = $_GET['name'];

// Escape any special characters in the parameter value
$escaped_name = urlencode($name);

// Now you can safely use the $escaped_name variable in your script
echo "Hello, " . $escaped_name;
