maxdb_fetch_array
(no version information, might be only in CVS) maxdb_fetch_array -- Fetch a result row as an associative, a numeric array, or both
DescriptionПроцедурный стиль: mixed maxdb_fetch_array ( resource result [, int resulttype] ) Returns an array that corresponds to the fetched row or NULL if there are no more rows for the
resultset represented by the result parameter.
maxdb_fetch_array() is an extended version of the
maxdb_fetch_row() function. In addition to storing the data in the
numeric indices of the result array, the maxdb_fetch_array() function can
also store the data in associative indices, using the field names of the result set as keys.
Замечание: Имена полей, возвращаемые этой
функцией, регистро-зависимы.
Замечание: Эта функция устанавливает NULL-поля
в значение NULL PHP.
If two or more columns of the result have the same field names, the last column will take
precedence and overwrite the earlier data. In order to access multiple columns with the same
name, the numerically indexed version of the row must be used.
The optional second argument resulttype is a constant indicating what
type of array should be produced from the current row data. Возможные значения для this parameter
are the constants MAXDB_ASSOC, MAXDB_NUM, or MAXDB_BOTH. By default the
maxdb_fetch_array() function will assume MAXDB_BOTH for this parameter.
By using the MAXDB_ASSOC constant this function will behave identically to the
maxdb_fetch_assoc(), while MAXDB_NUM will behave identically to the
maxdb_fetch_row() function. The final option MAXDB_BOTH will create a single
array with the attributes of both.
Return valuesReturns an array that corresponds to the fetched row or NULL if there are no more rows in resultset.
Example
Пример 1. Процедурный стиль
<?php
$link
=
maxdb_connect
(
"localhost"
,
"MONA"
,
"RED"
);
/* check connection */
if (
maxdb_connect_errno
()) {
printf
(
"Connect failed: %s\n"
,
maxdb_connect_error
());
exit();
}
$query
=
"SELECT name, state FROM hotel.city ORDER by zip"
;
$result
=
maxdb_query
(
$link
,
$query
);
/* numeric array */
$row
=
maxdb_fetch_array
(
$result
,
MAXDB_NUM
);
printf
(
"%s (%s)\n"
,
$row
[
0
],
$row
[
1
]);
/* associative array */
$row
=
maxdb_fetch_array
(
$result
,
MAXDB_ASSOC
);
printf
(
"%s (%s)\n"
,
$row
[
"NAME"
],
$row
[
"STATE"
]);
/* associative and numeric array */
$row
=
maxdb_fetch_array
(
$result
,
MAXDB_BOTH
);
printf
(
"%s (%s)\n"
,
$row
[
0
],
$row
[
"STATE"
]);
/* free result set */
maxdb_free_result
(
$result
);
/* close connection */
maxdb_close
(
$link
);
?>
