Cannot instantiate a PDO object in PHP MVC framework

Question

Hello,

Can anyone help me with this?

I have this function in a singleton class. The error it is giving me back is that it cannot find the class.

First I thought it had something to do with the autoloader, but I did spl_autoload_unregister('libloader') and it still gives the same error?

The host is running php 5.

public static function getInstantie()
    {
     if (!self::$instantie)
     {
      $config = config::getInstantie();
      $db_type = $config->config_waarden['database']['db_type'];
      $hostnaam = $config->config_waarden['database']['db_hostnaam'];
      $dbnaam = $config->config_waarden['database']['db_naam'];
      $db_wachtwoord = $config->config_waarden['database']['db_wachtwoord'];
      $db_gebruikersnaam = $config->config_waarden['database']['db_gebruikersnaam'];
      $db_poort = $config->config_waarden['database']['db_poort'];

     self::$instantie = new PDO("$db_type:host=$hostnaam;port=$db_poort;dbname=$dbnaam",$db_gebruikersnaam, $db_wachtwoord);
      self::$instantie-> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
     }
     return self::$instantie;
    }

thanks, Richard

Answer 1

is that function inside of a class that extends PDO? If not, can you try to make that function inside of a class that extends PDO and instead of self call the functions using keyword parent?

Answer 2

PDO is enabled by default with a set of database drivers:

http://au.php.net/manual/en/pdo.installation.php

But the build of PHP you are working with could have it disabled. Autoloading will have no effect on whether or not the PDO class will be found.

Create a PHP info file and check to see if the PDO section exists. If it doesn't, then your issue is most likely because it wasn't built into your php installation.
