pg_fetch_assoc

(PHP 4 >= 4.3.0, PHP 5)pg_fetch_assoc -- Fetch a row as an associative array

Описание

array pg_fetch_assoc (resource result [, int row])

pg_fetch_assoc() returns an associative array that

corresponds to the fetched row (records).

pg_fetch_assoc() is equivalent to calling

pg_fetch_array() with PGSQL_ASSOC as the

optional third parameter. It only returns an associative array.

If you need the numeric indices, use

pg_fetch_row().

Замечание: Эта функция устанавливает NULL-поля

в значение NULL PHP.

pg_fetch_assoc() is NOT significantly

slower than using pg_fetch_row(), and

is significantly easier to use.

Замечание:

row became optional in PHP 4.1.0.

Список параметров

result

PostgreSQL query result resource, returned by pg_query(),

pg_query_params() or pg_execute()

(among others).

row

Row number in result to fetch. Rows are numbered from 0 upwards. If omitted,

next row is fetched.

Возвращаемые значения

An array indexed associatively (by field name).

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.
