Hi Alex,
Unfortunately, I can't find any way to catch errors that PHP considers
"Fatal". I tried try/catch, set_error_handler(), and error_reporting, none of
which seem to be able to catch this.
This is, however, really a programming error. The pg_* functions shouldn't be
being called if they don't exist. Therefore, your query method could be
rewritten like this, which does solve the problem:
<?php
define("ApplicationError_FunctionUnavailable", 1);
class class_fail
{
function method_query($params, $error)
{
if (! function_exists("pg_connect") ||
! function_exists("pg_query"))
{
$error->SetError(ApplicationError_FunctionUnavailable,
"pg_* functions are unavailable");
return $error;
}
$db = pg_connect("host=localhost dbname=test user=postgres");
$query = "SELECT * FROM test";
$result = pg_query($query);
return pg_fetch_row($result);
}
}
?>
I hope this helps. If you know of a way in PHP to provide a more general
solution at the server level, please let me know!
(It's probably only necessary to do a single function_exists() call. If
pg_connect exists, pg_query will too (and pg_fetch_row, which I didn't check
for.)
Cheers,
Derrell
