Abstracting Oracle Connectivity with PHP/OCI8 - Switching Between Development, QA and Production Environments

(Page 6 of 7 )

We created that OCI8Hook class with database login and password abstraction for a reason.

In many corporations, you'll have multiple environments. You'll want to build your code against the development environment, test it on a QA environment and finally if all goes well, send it out to a production environment. Well, that's one more advantage to having your connection strings abstracted into the function getDBAuth($sid) { ... } function.

To toggle between environments, simple change the connect string for your DBNAME. Say I'm running all my queries against 'DBXYZ' with the following $stmt = $this->query("DBXYZ", $sql, $bargs);. Well, by simply changing the connect string from this:

case "DBXYZ": return (array("usernam1", "secret1", "DBXYZ"));
To something like this:

case "DBXYZ": return (array("usernam1", "secret1", "TESTDB"));

Or if you wanted to be really fancy, you might consider sticking an IF statement in there like this:

case "DBXYZ":
if (--I'm on the DEV environment--)
{
return (array("usernam1", "secret1", "DEVDB"));
else if (--I'm on the QA environment--)
{
return (array("usernam1", "secret1", "TESTDB"));
}
else
{
return (array("usernam1", "secret1", "PRODDB"));
}
...
