# db2_fetch_both

(PECL ibm_db2 >= 1.0.0)

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

### Opis

array db2_fetch_both ( resource `$stmt` [, int `$row_number` = -1 ] )

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().

### Parametry

`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.

### Zwracane wartości

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.

### Przykłady

Przykład #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]);
}
?>`

    5     Rickety Ride     goat                                   9.70
    2     Smarty           horse                                350.00

Przykład #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;
}
?>`

    5     Rickety Ride     goat                                   9.70
    2     Smarty           horse                                350.00
