db2_fetch_both — Returns an array, indexed by both column name and position, representing a row in a result set
Описание
$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().
Список параметров
-
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.
Возвращаемые значения
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.
Примеры
Пример #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]);
}
?>
Результат выполнения данного примера:
0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00
Пример #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;
}
?>
Результат выполнения данного примера:
0 Pook cat 3.20 5 Rickety Ride goat 9.70 2 Smarty horse 350.00
