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 (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().

注: This function sets NULL fields to PHP NULL value.

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

注: row became optional in PHP 4.1.0.

Parameters

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.

Return Values

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.
