pg_fetch_assoc

(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

pg_fetch_assoc — Fetch a row as an associative array

Description

pg_fetch_assoc(PgSql\Result $result, ?int $row = null): array|false

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: This function sets NULL fields to the PHP null value.

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

Parameters

result: An PgSql\Result instance, 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 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.

Changelog

Version	Description
8.1.0	The `result` parameter expects an PgSql\Result instance now; previously, a resource was expected.
