Re: [PHP-DB] Limited connections to the database. .
Sorry, I should've replied to your post first, but, have you tried
manually limiting the connections via PHP?
Code used from Omega Engine (Copyright Omega Vortex):
$ini_data = $engine-ini_data['file'];
setup_errors();
if ($ini_data['DB']['connections'] 5) {
$engine-error = There are too many connections to the database,
please try again later.;
$engine-toggle_errbits(ERR_CONNECT);
$engine-engine_die();
}
That code checks the connections value in the ini file to see if it's
greater than 5, if it is, it returns an error telling the visitor to try
again later.
Please note in order to make this work, at least 2-3 other functions
would have to be used. I'd be more than happy to write them for you if
you need it.

Some good ideas in this (http://marc.theaimsgroup.com/?l=php-devm=98193543028899w=2) post...
