# pg_fetch_assoc

(PHP 4 >= 4.3.0, PHP 5)

pg_fetch_assoc -- Fetch a row as an associative array

## Description

array pg_fetch_assoc ( resource result [, int row])

pg_fetch_assoc() returns an associative array that corresponds to the fetched row (tuples/records). It returns `FALSE`, if there are no more rows.

pg_fetch_assoc() is equivalent to calling pg_fetch_array() with PGSQL_ASSOC for the optional third parameter. It only returns an associative array. If you need the numeric indices, use pg_fetch_row().

> 備注:This function sets NULL fields to PHP `NULL` value.

row is row (record) number to be retrieved. First row is 0.

pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), while it provides a significant ease of use.

示範 1.pg_fetch_assoc() example
`<?php $conn = pg_connect("dbname=publisher"); if (!$conn) { echo "An error occured.\n"; exit; } $result = pg_query($conn, "SELECT id, author, email FROM authors"); if (!$result) { echo "An error occured.\n"; exit; } while ($row = pg_fetch_assoc($result)) { echo $row['id']; echo $row['author']; echo $row['email']; } ?>`
