What are common issues with handling special characters like backslashes in PHP text input fields?

Special characters like backslashes can cause issues when handling text input fields in PHP because they are often used as escape characters. To handle these special characters properly, you can use the PHP function addslashes() to add backslashes before characters like quotes, backslashes, and NULL bytes. This function will ensure that the input is properly escaped and can be safely stored or processed in your PHP application. 

$input = $_POST['input_field'];
$escaped_input = addslashes($input);

// Now $escaped_input can be safely used in your PHP application
