How can backslashes be prevented from appearing when modifying a PHP file with user input?

To prevent backslashes from appearing when modifying a PHP file with user input, you can use the stripslashes() function in PHP. This function removes backslashes from a string, which can help prevent unintended characters from being inserted into the file. 

$user_input = $_POST['user_input']; // Assuming user input is received via POST method
$clean_input = stripslashes($user_input);

// Now you can use $clean_input in your PHP file without worrying about backslashes
