Use Namespaces in PHP 5.2 If Statement

Question

Is it possible to use some sort of check before adding namespaces to a script that might be run on a php 5.2 server?

For example, if you want to use doctrine(which requires 5.3) on a 5.3 server, and fallback to PDO on a 5.2 server.

Example:

if($pdo){

  //RETURN a pdo connection

}
else if($doctrine){

   //this will fail even if doctrine is false because namespaces are being used
   $classLoader = new Doctrine\Common\ClassLoader('Doctrine\Common');  
   $classLoader->register();

}

This is just an example, I am sure I can get this to work without namespaces, but just wondering if there is anyway to use them within an IF statement.

Answer 1

You could tuck the Doctrine code into a separate PHP file and require() it inside the else if branch.
