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 servers that display selected PHP configuration settings for the server.

So I am looking to see if there is a command I can use.

Answer 1

The proper way of determining that will be using the extension_loaded function:-

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

And you might also want to check for the database-specific PDO driver using:-

if ( extension_loaded('pdo_<database type here>') ) { // e.g., pdo_mysql     ....... } 

Answer 2

Check if the class exists:

if (class_exists('PDO')) 

I appreciate the support and all the upvotes I still get, but please check Salman Abbas's answer for the proper way to do this.
