Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The is no such ini entries. ini_get() only works for settings defined by PHP.

The manual [1] describes this as an INI option like any other:
| pdo.dsn.* string [php.ini only]

So it should be possible to use ini_get() to get the value.

Interesting. But well in the sense of PHP they don't exist but PDO uses a hack to use them anyways. I doubt ini_get should use such hacks.

With get_cfg_var() I can get such values:
| var_dump(get_cfg_var('pdo.dsn.test'));
| string(15) "sqlite::memory:"

| 5.3.0   get_cfg_var() was fixed to be able to return "array" ini options. 

(At least the manual should describe this restriction for ini_get[_all] or phpinfo.)

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
