pg_fetch_assoc — Fetch a row as an associative array
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.
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.
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.
