How can text editors like Notepad++ help identify and remove non-printable characters in PHP code?

Non-printable characters in PHP code can cause syntax errors and unexpected behavior. Text editors like Notepad++ can help identify and remove these characters by enabling the display of special characters such as tabs, line breaks, and non-printable characters. By visually inspecting the code and removing any unusual characters, you can ensure that the PHP code runs smoothly without any issues. 

// Example PHP code snippet to remove non-printable characters using Notepad++
$code = file_get_contents('example.php');

// Remove non-printable characters
$cleaned_code = preg_replace('/[[:^print:]]/', '', $code);

// Save the cleaned code back to the file
file_put_contents('example.php', $cleaned_code);
