What is the difference between mysql_fetch_row () and mysql_fetch_array?

------ Solution --------------------
The two functions return an array. The difference is that the array returned by the first function only contains values. we can only $ row [0], $ row [1], in this way, the data is read by the array subscript, while the array returned by MySQL_fetch_array () contains both the first and key-value pairs. we can read the data in this way, (assume that the database field is username, passwd ):

$ Row ['username'], $ row ['passwd']
------ Solution --------------------
Mysql_fetch_row is a one-row array from the result set, which is used as an enumeration

Mysql_fetch_array is used to retrieve an array from the result set as an associated array or a number array.


Eg:
$ SQL = "select abc, def from ";
$ Res = mysql_query ($ SQL );

So:
$ Row = mysql_fetch_row ($ res );
$ Row: $ row [0] and $ row [1]
So:
$ Row = mysql_fetch_array ($ res );
$ Row results are 4: $ row [0], $ row [1], $ row ["abc"], and $ row ["def"]
