Use array_key_exists() to determine whether the key is set, and it can be recognized even if the value is null; 3. Use the empty merge operator?? to set the default value to avoid directly accessing undefined keys; in addition, you need to pay attention to common problems such as the spelling of form field names, the database result is empty, the array unpacking is not verified, the child keys are not checked in foreach, and the session_start() is not called.
