db2_fetch_both

(PECL)

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

Description

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().

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
