This function will mask part of the the user portion of an Email address (everything before the @)

This function compares two strings.

Many parts of the codebase have a convention of internally passing around HTML-encoded URLs. This effectively means that "&" is replaced by "&" (because most other odd characters are %-escaped in URLs; and %-escaped strings don't need any extra escaping in HTML).

When a user supplies a URL (e.g. to an image), we'd like to: - Remove the protocol and domain name if the URL points to the current site.

• Keep the domain name for remote URLs.
  • Optionally, force remote URLs to use https instead of http (which is useful for images)

Safely unserialize a string of scalar or array values (but not objects!)

Use xkerman/restricted-unserialize to unserialize strings using PHP's serialization format. restricted-unserialize works like PHP's built-in unserialize function except that it does not deserialize object instances, making it immune to PHP Object Injection {see https://www.owasp.org/index.php/PHP_Object_Injection} vulnerabilities.

Note: When dealing with user inputs, it is generally recommended to use safe, standard data interchange formats such as JSON rather than PHP's serialization format when dealing with user input.
