pg_fetch_assoc — Fetch a row as an associative array
Popis
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: Táto funkcie nastavuje NULL políčka na PHP NULL hodnotu.
pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), and is significantly easier to use.

-
PostgreSQL query result resource, 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, next row is fetched.
Vrátené hodnoty
An array indexed associatively (by field name). Each value in the array is represented as a string. Database NULL values are returned as NULL.
