How can PHP scripts be modified to limit the number of characters in user entries?
To limit the number of characters in user entries, you can use the `substr()` function in PHP to truncate the input to a specified length. This can help prevent excessively long inputs from being processed or stored in the database.
// Limit the number of characters in user input to 100
$user_input = $_POST['user_input'];
$limited_input = substr($user_input, 0, 100);
// Use $limited_input in your code instead of $user_input
