array pg_fetch_array ( resource result [, int row [, int result_type]] )
pg_fetch_array() returns an array that
corresponds to the fetched row (record).
pg_fetch_array() is an extended version of
pg_fetch_row(). In addition to storing the
data in the numeric indices (field number) to the result array, it
can also store the data using associative indices (field name).
It stores both indicies by default.
Замечание: Эта функция устанавливает NULL-поля
в значение NULL PHP.
pg_fetch_array() is NOT significantly
slower than using pg_fetch_row(), and
is significantly easier to use.
Row number in result to fetch. Rows are numbered from 0 upwards. If omitted,
next row is fetched.
result_type
An optional parameter that controls
how the returned array is indexed.
result_type is a constant and can take the
following values: PGSQL_ASSOC,
PGSQL_NUM and PGSQL_BOTH.
Using PGSQL_NUM, pg_fetch_array()
will return an array with numerical indices, using
PGSQL_ASSOC it will return only associative indices
while PGSQL_BOTH, the default, will return both
numerical and associative indices.
Возвращаемые значения
An array indexed numerically (beginning with 0) or
associatively (indexed by field name), or both.
Each value in the array is represented as a
string. Database NULL
values are returned as NULL.
FALSE is returned if row exceeds the number
of rows in the set, there are no more rows, or on any other error.
// As of PHP 4.1.0, the row parameter is optional; NULL can be passed instead, // to pass a result_type. Successive calls to pg_fetch_array will return the // next row. $arr = pg_fetch_array($result, NULL, PGSQL_ASSOC); echo $arr["author"] . " <- Row 2 Author\n"; echo $arr["email"] . " <- Row 2 E-mail\n";
