# db2_fetch_array

(PECL ibm_db2 >= 1.0.1)

db2_fetch_array — Returns an array, indexed by column position, representing a row in a result set

### 설명

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.

### 인수

`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.

### 반환값

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.

### 예제

Example #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]);
}
?>`

    2     Smarty           horse                                350.00

Example #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;
}
?>`

    5     Rickety Ride     goat                                   9.70
    2     Smarty           horse                                350.00
