# pg_fetch_assoc

(PHP 4 >= 4.3.0, PHP 5)

pg_fetch_assoc — Fetch a row as an associative array

### Descripción

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().

> Note: Esta funcion define campos NULL como valores PHP `NULL`.

pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), and is significantly easier to use.

### Lista de parámetros

`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.

### Valores retornados

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.
