PDO Oracle Driver PHP 7.4 Nginx

I am facing an issue with PDO Oracle Driver PHP 7.4 Nginx, I am not getting a proper solution or instruction on how to install that, can anyone please help

Code

try {
    $conn = new PDO('oci:dbname=//development.czeika65wu6y.us-east-1.rds.amazonaws.com:1521/xe/ORCL', 'xxxx', 'xxxxx');
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    } catch(PDOException $e) {
       echo 'ERROR: ' . $e->getMessage();
    }

Getting ERROR: could not find driver
