Troubleshooting "PHP Fatal Error: Class 'PDO' Not Found"

Background:

The PDO (PHP Data Objects) extension is a database abstraction layer that allows PHP scripts to connect to various database management systems (DBMS) using a consistent API.

Problem Description:

When using PHP, you may encounter the following error:

PHP Fatal error: Class 'PDO' not found

Causes:

There are several possible reasons for this error:

• The PDO extension is not installed or loaded.
• The PHP script is not using the correct syntax to access the PDO class.
• The MySQL extension, which is a PDO driver for MySQL, may be missing.

Solution:

1. Check PDO and MySQL Extensions:

• Verify that the PDO and PDO_MySQL extensions are installed and enabled in your PHP configuration. You can do this by checking your phpinfo() output.
• If the extensions are not installed or enabled, install them using the following commands:

yum install php-pdo
yum install php-pdo_mysql

2. Restart Web Server:

• After installing the extensions, restart your web server (e.g., Apache or Nginx) to load the changes.

3. Update PHP Code:

• Ensure that your PHP script is using the correct syntax to access the PDO class. The example code you provided should be updated as follows:

/**
 * Check whether the MySQL extension is installed/loaded
 *
 * @return boolean
 */
public function enabled() {
    return in_array('mysql', PDO::getAvailableDrivers());
}
