pg_fetch_assoc — Fetch a row as an associative array

Опис

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().

Зауваження: Ця функція встановлює NULL-полям значення PHP null.

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

Параметри

result: Примірник PgSql\Result, якого повертає одна з функцій pg_query(), pg_query_params() або pg_execute() (серед інших).
row: Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or null, the next row is fetched.

Значення, що повертаються

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.
