I have a DB wrapper class that uses PDO and in the constructor I create a PDO object. The wrapper class is in our namespace and we are using an autoloader. The issue is that the PDO class cannot be found within our namespace, so I tried using the global namespace as described here.
//Class file
namespace Company\Common;
class DB {
private function __construct(){
$this->Handle=new PDO(...);
}
}
With this, I get this (as expected):
Warning: require(...\vendors\Company\Common\PDO.class.php): failed to open stream
If I do this:
namespace Company\Common;
use PDO;
I get this:
Fatal error: Class 'DB' not found in ...\includes\utils.php
And utils.php contains this on the error line, which worked fine before implementing namespaces:
DB::getInstance();
Alternatively I tried this:
namespace Company\Common;
class DB {
private function __construct(){
$this->Handle=new \PDO(...);
}
}
Which tried to load the PDO class within our namespace as it originally did.
How can I resolve this? I thought by doing use PDO or new \PDO it would load the global PDO class, but it doesn't seem to be working?
Solved it. I didn't realize that aliasing a namespace only applies to the current file, and not any future included files. Found this on PHP.net which also applies to aliasing:
Importing rules are per file basis, meaning included files will NOT inherit the parent file's importing rules.
