As far as I can see, SELECTing VARRAYs is not supported by PHP's oci8
extension. It has some support for collection types as binds into PL/SQL calls,
but I can't spot any way to get it to work for defines.
Consider the below that shows it works for binds, at least:
Given that the following has been run against your definitions above:
insert into person values (1, 'Alice', 'McExample', t_fav_food(1, 2));
<?php
$conn = oci_connect('test', 'test', 'xe_excession');
$array = array();
$query = 'begin select favourite_food into :favourite_food from person where
person_id = 1; end;';
$statement = oci_parse($conn, $query);
$col = oci_new_collection($conn, 'T_FAV_FOOD');
oci_bind_by_name($statement, 'FAVOURITE_FOOD', $col, -1, SQLT_NTY);
$result = ociexecute($statement);
for ($i = 0; $i < $col->size(); $i++)
{
print $col->getElem($i) . "<br>";
}
?>
Output:
1
2
I'm using the newer function names since I'm on PHP5 and using the latest oci8
extension; I don't know what state of collections support was present in the
version of oci8 bundled with 4.4.4 - you can upgrade the oci8 extension
separately from PECL (and this is strongly recommended given the large overhaul
it got in version 1.1).
