How to determine if PDO is enabled in PHP?

Question

Is there a PHP command I can use to determine if PDO is enabled or disabled?

I know I an manually run phpinfo() and eyeball it, but I have a script I run various web

Answer 1

You have two options:

if (extension_loaded('pdo')) { /* ... */ }

Or (this one is not 100% reliable since it can be implemented in user-land classes):

if (class_exists('PDO', false)) { /* ... */ }

Personally, I prefer the first option.
