PDO Connection Test

Question

I am writing an installer for one of my apps and I would like to be able to test some default database settings.

Is this possible using PDO to test valid and invalid

As @Sascha Galley already mentioned you should set error mode to exception mode. However, you should also set up PDO::ATTR_TIMEOUT attribute to prevent a long time waiting for response in some cases.

Although documentation says that behavior of this attribute is driver-dependent in case of MySQL it's a connection timeout. You won't find anything about it documentation but here's a short snippet from driver's source code:

long connect_timeout = pdo_attr_lval(driver_options, PDO_ATTR_TIMEOUT, 30 TSRMLS_CC);
