说明

过程化风格

mixed maxdb_fetch_row ( resource $result )

面向对象风格

mixed maxdb_result::fetch_row ( void )

Returns an array that corresponds to the fetched row, or NULL if there are no more rows.

maxdb_fetch_row() fetches one row of data from the result set represented by result and returns it as an enumerated array, where each column is stored in an array offset starting from 0 (zero). Each subsequent call to the maxdb_fetch_row() function will return the next row within the result set, or FALSE if there are no more rows.

返回值

maxdb_fetch_row() returns an array that corresponds to the fetched row or NULL if there are no more rows in result set.

Note: 此函数将 NULL 字段设置为 PHP NULL 值。
