PHP5+SQLite+Ubuntu环境下PDO连接失败：找不到驱动求助

I’ve successfully set up PHP5 with SQLite in the past, but I’m hitting a frustrating roadblock trying to connect to a SQLite database via PDO right now. Here’s the connection code I’m using:

$dblocation = "path/to/database.db"; 
$dbConn = new PDO("sqlite:" . $dblocation);

When I execute this code, I get the following error message:

Connection Failed: Could not find driver.

I’ve gone through several troubleshooting steps to fix this issue, but none have worked so far:

• Checked SQLite3 support using php -a -c /etc/php5/cli/php.ini and phpinfo()—the output confirms SQLite3 is enabled:

  sqlite3 SQLite3 support => enabled SQLite3 module version => 0.7-dev SQLite Library => 3.8.2
  

• Verified available PDO drivers, which include both mysql and sqlite:

  php > print_r(PDO::getAvailableDrivers());
  Array ( [0] => mysql [1] => sqlite )
  php >
  

• Enabled pdo and pdo_sqlite in Apache2; I didn’t uncomment the extension lines in php.ini because that caused duplicate loading errors.
• Uninstalled and reinstalled all PHP PDO components.
• Uninstalled and reinstalled PHP itself entirely.

Everything seems to check out configuration-wise, but the driver error still persists. I’m stuck and would really appreciate any technical advice or insights from the community to get this working again.
