This function fetches the next row from a result set. The function returns NULL if there are no more rows in the result set to retrieve or if an error occurs. Here is its syntax:

MYSQL_ROW mysql_fetch_row(MYSQL_RES *resultset)

Here, the resultset parameter is the set from which the next row has to be fetched. You can access values in the column of the row by using the subscript row[0], row[1], and so on, where row[0] represents the data in the first column, row[1] represents the data in the second column, and so on.
