Описание

array db2_fetch_array ( resource stmt [, int row_number] )


- Returns an array, indexed by column position, representing a row in a result set. The columns are 0-indexed.

Список параметров

-

stmt

- A valid stmt resource containing a result set.

row_number

- Requests a specific 1-indexed row from the result set. Passing this parameter results in a PHP warning if the result set uses a forward-only cursor.

Возвращаемые значения

- Returns a 0-indexed array with column values indexed by the column position representing the next or requested row in the result set. Returns FALSE if there are no rows left in the result set, or if the row requested by row_number does not exist in the result set.

Примеры

-

Пример 1. Iterating through a forward-only cursor

- If you call db2_fetch_array() without a specific row number, it automatically retrieves the next row in the result set.

<?php

$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$stmt = db2_prepare($conn, $sql);
$result = db2_execute($stmt, $sql);

while ($row = db2_fetch_array($result)) {
printf ("%-5d %-16s %-32s %10s\n",
$row[0], $row[1], $row[2], $row[3]);
}
?>

Результат выполнения данного примера:
0 Pook cat 3.20

5 Rickety Ride goat 9.70

2 Smarty horse 350.00

Пример 2. Retrieving specific rows with db2_fetch_assoc() from a scrollable cursor

- If your result set uses a scrollable cursor, you can call db2_fetch_assoc() with a specific row number. The following example retrieves every other row in the result set, starting with the second row.

<?php

$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$result = db2_exec($stmt, $sql, array('cursor' => DB2_SCROLLABLE));

$i=2;
while ($row = db2_fetch_array($result, $i)) {
printf ("%-5d %-16s %-32s %10s\n",
$row[0], $row[1], $row[2], $row[3]);
$i = $i + 2;
}
?>

Результат выполнения данного примера:
0 Pook cat 3.20

5 Rickety Ride goat 9.70

2 Smarty horse 350.00
