Question

How can I detect, using php, if the machine has oracle (oci8 and/or pdo_oci) installed?

I'm working on a PHP project where some developers, such as myself, have it installed, but there's little need for the themers to have it. How can I write a quick function to use in the code so that my themers are able to work on the look of the site without having it crash on them?

Answer 1

if the oci extension isn't installed, then you'll get a fatal error with farside.myopenid.com's answer, you can use function_exists('oci_connect') or extension_loaded('oci8') (or whatever the extension's actually called)
