pg_fetch_assoc

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

    pg_fetch_assoc — Fetch a row as an associative array

    Descrição

    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().

    Nota: Esta função define campos NULL como o valor null do PHP.

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

    Parâmetros

    result

    Uma instância de PgSql\Result, retornada por pg_query(), pg_query_params() ou pg_execute() (entre outras).

    row

    Row number in result to fetch. Rows are numbered from 0 upwards. If omitted or null, the next row is fetched.

    Valor Retornado

    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.
