Problems with PHP namespaces and built-in classes, how to fix?

Question

I\'m writing a small library in PHP and i\'m having some problems with built-in classes not being read. For example:

namespace Woody;

class Test {
  public          


        

Answer 1

This:

namespace Woody;
use PDO;

Or:

$db = new \PDO(params);

Point in case is, that the class PDO is not a full qualified name within your Namespace, so PHP would look for Woody\PDO which is not available.

See Name resolution rulesDocs for a detailed description how class names are resolved to a Fully qualified name.
