pg_fetch_assoc

(PHP 4 >= 4.3.0, PHP 5)

pg_fetch_assoc -- Fetch a row as an associative array

Opis

array pg_fetch_assoc ( resource result [, int row] )

pg_fetch_assoc() returns an associative array that corresponds to the fetched row (tuples/records). It returns FALSE, if there are no more rows.

pg_fetch_assoc() is equivalent to calling pg_fetch_array() with PGSQL_ASSOC for the optional third parameter. It only returns an associative array. If you need the numeric indices, use pg_fetch_row().

Notatka: This function sets NULL fields to PHP NULL value.

row is row (record) number to be retrieved. First row is 0.

pg_fetch_assoc() is NOT significantly slower than using pg_fetch_row(), while it provides a significant ease of use.

Notatka: From 4.1.0, row became optional. Calling pg_fetch_assoc() will increment the internal row counter by one.
