db2_fetch_assoc — Returns an array, indexed by column name, representing a row in a result set
$stmt
[, int $row_number = -1
] )Returns an array, indexed by column name, representing a row in a result set.
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.
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.
Przykład #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.
<?php
$sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed";
$stmt = db2_prepare($conn, $sql);
$result = db2_execute($stmt);
while ($row = db2_fetch_assoc($stmt)) {
printf ("%-5d %-16s %-32s %10s\n",
$row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']);
}
?>

Przykład #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.
<?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_assoc($result, $i)) {
printf ("%-5d %-16s %-32s %10s\n",
$row['ID'], $row['NAME'], $row['BREED'], $row['WEIGHT']);
$i = $i + 2;
}
?>
