# db2_fetch_both

(PECL)

db2_fetch_both -- Returns an array, indexed by both column name and position, representing a row in a result set

## Descrizione

array db2_fetch_both ( resource stmt [, int row_number] )

Returns an array, indexed by both column name and position, representing a row in a result set. Note that the row returned by db2_fetch_both() requires more memory than the single-indexed arrays returned by db2_fetch_assoc() or db2_fetch_array().

## Elenco dei parametri

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.

## Valori restituiti

Returns an associative array with column values indexed by both the column name and 0-indexed column number. The array represents 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.

## Esempi

Esempio 1. Iterating through a forward-only cursor

If you call db2_fetch_both() without a specific row number, it automatically retrieves the next row in the result set. The following example accesses columns in the returned array by both column name and by numeric index.

`<?php $sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed"; $stmt = db2_prepare($conn, $sql); $result = db2_execute($stmt); while ($row = db2_fetch_both($stmt)) { printf ("%-5d %-16s %-32s %10s\n", $row['ID'], $row[0], $row['BREED'], $row[3]); } ?>`

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

Esempio 2. Retrieving specific rows with db2_fetch_both() from a scrollable cursor

If your result set uses a scrollable cursor, you can call db2_fetch_both() 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_both($result, $i)) { printf ("%-5d %-16s %-32s %10s\n", $row[0], $row['NAME'], $row[2], $row['WEIGHT']); $i = $i + 2; } ?>`

Il precedente esempio visualizzerà:

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