When to use htmlspecialchars vs filter_input ?

So, in response to your inquiry, filter_input can also be used to prevent XSS attacks (provided you use an appropriate sanitization filter). However, I recommend not escaping user input before saving it to the database. It's better to save the user input as is, and then only escape it when it's being rendered/echoed to a browser.

When to use htmlspecialchars vs filter_input ?

The main reason I can think of is that htmlspecialchars exists in PHP for a long time and it has been retained for backwards compatibility, but that function has been generalized by the filter_input function as of PHP 5.2. While the htmlspecialchars will convert characters specific to HTML, such as the < and > to their equivalent HTML entity (< and >), the filter_input is configurable in regards to the type of filtering that it should perform. It can be made to behave in the same manner as the old htmlspecialchars by using the FILTER_SANITIZE_FULL_SPECIAL_CHARS. But there are many other filters available. For example, it's also typically used to validate email addresses:

$isValidEmail = filter_input(INPUT_POST, "email", FILTER_VALIDATE_EMAIL);

if ($isValidEmail) {
  // ...
}

$isValidEmail = filter_input(INPUT_POST, "email", FILTER_VALIDATE_EMAIL);

if ($isValidEmail) {
  // ...
}

Not as far as I know. In fact, when you create a New Text File, no file is really created on your computer. A file is only created after it is saved. The New Text File command simply creates a new editor tab for temporary modification.
