pg_fetch_array -- Fetch a row as an array
Description
array pg_fetch_array (resource result, int row [, int
result_type])
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.
Note: 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_result().

Example 1. PostgreSQL fetch array
<?php
$conn = pg_pconnect ("dbname=publisher");
if (!$conn) {
echo "An error occured.\n";
exit;
}
$result = pg_exec ($conn, "SELECT * FROM authors");
if (!$result) {
echo "An error occured.\n";
exit;
}
$arr = pg_fetch_array ($result, 0, PGSQL_NUM);
echo $arr[0] . " <- array\n";
$arr = pg_fetch_array ($result, 1, PGSQL_ASSOC);
echo $arr["author"] . " <- array\n";
?>
