db2_fetch_array

Returns an array, indexed by column position, representing a row in a result set

Beschreibung

array db2_fetch_array ( resource $stmt [, int $row_number = -1 ] )

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

Parameter-Liste

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.

Rückgabewerte

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.

Beispiele

Beispiel #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);

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

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

0     Pook             cat                                    3.20
5     Rickety Ride     goat                                   9.70
2     Smarty           horse                                350.00

Beispiel #2 Retrieving specific rows with db2_fetch_array from a scrollable cursor

If your result set uses a scrollable cursor, you can call db2_fetch_array 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;
}
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

0     Pook             cat                                    3.20
5     Rickety Ride     goat                                   9.70
2     Smarty           horse                                350.00
