db2_fetch_assoc

(PECL)

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

A valid stmt resource containing a result set.

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.

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.

Example 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.

 
$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']);
}

The above example will output:

Example 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.

 
$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;
}

The above example will output:
