??? A. You can use the mysql_fetch_array function to obtain the value through the key name (field name) and number key. For example, $ row ["user"] and $ row [0]

??? B. mysql_fetch_row can only obtain field values through the number key. For example, $ row [0]

???????? How to get the value: $ row-> user.
