    The question is quite wide. What you need to pay attention.

    • Always check parameters (especially $_GET, $_POST, $_COOKIE ), for example, check that cities are cities, and numbers are numbers.
    • Use strong authentication ( PEAR::Auth , etc.).
    • Ensure that server settings do not allow reading sensitive session data from outside.
    • Always filter external data ( htmlspecialchars , etc.) when displaying.
    • Take measures to protect against SQL injection ( mysql_real_escape_string , etc.).

      The answer lies in the search!
