# 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

### Description

db2_fetch_both(resource `$stmt`, int `$row_number` = -1): array|false

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().

### Parameters

`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.

### Return Values

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.

### Examples

Example #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]);
    }
    ?>

The above example will output:

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

Example #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;
    }
    ?>

The above example will output:

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