pg_fetch_assoc

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

pg_fetch_assocFetch a row as an associative array

Descrierea

pg_fetch_assoc ( resource $result [, int $row ] ) : 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().

Notă: Această funcție stabilește câmpurile NULL la valoarea PHP NULL.

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

Parametri

result

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 or NULL, the next row is fetched.

Valorile întoarse

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.
