PG_FETCH_ASSOC(3) PG_FETCH_ASSOC(3)
pg_fetch_assoc - Fetch a row as an associative array
SYNOPSIS
array pg_fetch_assoc (resource $result, [int $row])
DESCRIPTION
pg_fetch_assoc(3) returns an associative array that corresponds to the fetched row (records).
pg_fetch_assoc(3) is equivalent to calling pg_fetch_array(3) with PGSQL_ASSOC as the optional third parameter. It only returns an associa-
tive array. If you need the numeric indices, use pg_fetch_row(3).
Note
This function sets NULL fields to the PHP NULL value.
pg_fetch_assoc(3) is NOT significantly slower than using pg_fetch_row(3), and is significantly easier to use.
PARAMETERS
o $result
- PostgreSQL query result resource, returned by pg_query(3), pg_query_params(3) or pg_execute(3) (among others).
o $row
- Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or NULL, the 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.
