mysqli_fetch_assoc (PHP 5) mysqli_fetch_assoc (no version information, might be only in CVS) mysqli->fetch_assoc -- Fetch a result row as an associative array DescriptionProcedural style: array mysqli_fetch_assoc ( mysqli_result result ) Object oriented style (method): class mysqli_result { array fetch_assoc ( void ) }
Returns an associative array that corresponds to the fetched row or NULL if there are
no more rows.
The mysqli_fetch_assoc() function is used to return an associative array
representing the next row in the result set for the result represented by the
result parameter, where each key in the array represents the name
of one of the result set's columns.
If two or more columns of the result have the same field names,
the last column will take precedence. To access the other
column(s) of the same name, you either need to access the
result with numeric indices by using
mysqli_fetch_row() or add alias names.
注: 本函数对
PHP NULL 值设定 NULL 字段。
返回值
Returns an array that corresponds to the fetched row or NULL if there are no more rows in resultset.
