# db2_fetch_assoc

(PECL)

db2_fetch_assoc -- Returns an array, indexed by column name, representing a row in a result set

## Leírás

array db2_fetch_assoc ( resource stmt [, int row_number] )

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

## Paraméterek

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.

## Visszatérési értékek

Returns an associative array with column values indexed by the column name 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.

## Példák

Példa 1. Iterating through a forward-only cursor If you call db2_fetch_assoc() 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 ($row = db2_fetch_assoc($stmt)) { printf ("%-5d %-16s %-32s %10s\n", $row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']); } ?>`
A fenti példa a következő kimenetet adja:
    0     Pook             cat                                    3.20
    5     Rickety Ride     goat                                   9.70
    2     Smarty           horse                                350.00

Példa 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_assoc($result, $i)) { printf ("%-5d %-16s %-32s %10s\n", $row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']); $i = $i + 2; } ?>`
A fenti példa a következő kimenetet adja:
    0     Pook             cat                                    3.20
    5     Rickety Ride     goat                                   9.70
    2     Smarty           horse                                350.00
