My post below works but is *not* the correct way. It only works because of default behavior. I'll re-post my understanding of what is "correct" soon.

On the three versions of Linux/Ingres I've worked on, I've always had to modify the following line in the example above:
while ($iirelation = ingres_fetch_object($link)) {
to:
while ($iirelation = ingres_fetch_object()) {
If not, PHP will return "Undefined property" notices.
However, it's my understanding that the following is the proper way to access the database (it works as expected):
<?php
// Connecting, selecting database
$link = ingres_connect('database', 'user', 'password')
or die('Could not connect: ' . ingres_error($link));
echo 'Connected successfully';
// Select from a table that exists in all Ingres databases
$query = 'SELECT * FROM iirelation';
$rs = ingres_query($link,$query) or die('Query failed: ' .
ingres_error($link));
// Print results in HTML
// relid - table name
// relowner - table owner
echo "<table>\n";
while ($iirelation = ingres_fetch_object($rs)) {
echo "\t<tr>\n";
echo "\t\t<td>" . $iirelation->relid . "</td>\n";
echo "\t\t<td>" . $iirelation->relowner . "</td>\n";
echo "\t</tr>\n";
}
echo "</table>\n";
// Commit transaction
ingres_commit($link);
// Closing connection
ingres_close($link);
?>
