I'd start with the less-error prone (fewer brackets to mismatch) "Easy Connect" connection string.
See "Oracle Database Name Connection Identifiers" on page 102 of http://www.oracle.com/technetwork/topics/php/underground-php-oracle-manual-098250.html
In your case the command would be
$conn = oci_connect('user', 'pass', 'supertrain:1522/train');From googling, there are various configuration file fixes that might help. It's unlikely to be a PHP
issue, so you might want to follow up in a DB forum, e.g. Database Installation
