extract-user-data.php

• [High]Avoid PHP's extract() function
  The extract() function is prone to many vulnerabilities such as information disclosure and variable overwrite. It can be used to read arbitrary data if an attacker can control the names of variables that are passed to extract. Instead of extract(), parse the data using safer methods like foreach()
• [Low]Validate data before extract()
  Make sure the data being passed to the extract function is safe and not controlled by an attacker. Validate and sanitize data before passing it to the extract() function. Perform a data type check to ensure that the data passed to extract() is an array before using it.
