This hunk of code works fine on my php 4.3.2 / postgresql 7.3.4 box:
<?php
$conn = pg_connect("dbname=marl8412 user=marl8412");
$a = pg_query($conn,"prepare test (int4) as select * from accounts where
aid= $1");
$res = pg_query($conn,"execute test (45)");
$row = pg_fetch_row($res);
print implode(" ",array_values($row))."<BR>";
?>
so yes, you can use a prepared queries in PHP. But, they won't live
across connections I don't think. Or at least I'm pretty sure you can't
count on them living from one page to the next. but if you're gonna have
a page where you run the same select with different select parameters over
and over it might be a win.
