nullvalue.
resultAn PgSql\Result instance, returned by pg_query(), pg_query_params() or pg_execute()(among others).
mode

mode is a constant and can take the following values:
PGSQL_ASSOC, PGSQL_NUM and PGSQL_BOTH.
Using PGSQL_NUM, the function will return an array with numerical indices,
using PGSQL_ASSOC it will return only associative indices
while PGSQL_BOTH will return both numerical and associative indices.

instead of false for result sets with zero rows.

Example #1 PostgreSQL fetch all
<?php
$conn = pg_pconnect("dbname=publisher");
if (!$conn) {
echo "An error occurred.\n";
exit;
}
$result = pg_query($conn, "SELECT * FROM authors");
if (!$result) {
echo "An error occurred.\n";
exit;
}
$arr = pg_fetch_all($result);
print_r($arr);
?>The above example will output something similar to:
Array
(
[0] => Array
(
[id] => 1
[name] => Fred
)
[1] => Array
(
[id] => 2
[name] => Bob
)
)
