pg_fetch_array() returns an
array that corresponds to the fetched row (tuples/records).
It returns FALSE, if there
are no more rows.
pg_fetch_array() is an extended
version of pg_fetch_row(). In addition to storing the
data in the numeric indices (field index) to the result
array, it also stores the data in associative indices (field
name) by default.
row is row (record)
number to be retrieved. First row is 0.
result_type is
optional parameter controls how return value is initialized.
result_type is a constant
and can take the following values: PGSQL_ASSOC, PGSQL_NUM,
and PGSQL_BOTH. pg_fetch_array()
returns associative array that has field name as key for
PGSQL_ASSOC. field index as key with PGSQL_NUM and both field
name/index as key with PGSQL_BOTH. Default is PGSQL_BOTH.
注: result_type was added in PHP 4.0.
pg_fetch_array() is NOT
significantly slower than using
pg_fetch_row(), while it provides a significant ease
of use.
See also pg_fetch_row() and
pg_fetch_object() and
pg_fetch_result().
注: From 4.1.0, row became optional. Calling pg_fetch_array() will increment internal row counter by 1.
