mixed maxdb_fetch_row ( resource $result )

Objektorientierter Stil

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.

Rückgabewerte

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

Hinweis: Diese Funktion setzt NULL-Felder auf den PHP Wert-NULL.
