Is PDO better than MySQLi?
While both PDO and MySQLi are quite fast, MySQLi performs insignificantly faster in benchmarks – ~2.5% for non-prepared statements, and ~6.5% for prepared ones. Still, the native MySQL extension is even faster than both of these.
How can I get error in PDO?
PDO::errorInfo() only retrieves error information for operations performed directly on the database handle. If you create a PDOStatement object through PDO::prepare() or PDO::query() and invoke an error on the statement handle, PDO::errorInfo() will not reflect the error from the statement handle.
What is the purpose of PDO :: errorInfo () data?
PDO::errorInfo only retrieves error information for operations performed directly on the database. Use PDOStatement::errorInfo when a PDOStatement instance is created using PDO::prepare or PDO::query. Support for PDO was added in version 2.0 of the Microsoft Drivers for PHP for SQL Server.
Does WordPress use MySQLi or PDO?
If you want (need) PDO support, you can use the WP DB Driver plugin: wordpress.org/plugins/wp-db-driver. WordPress now defaults to mysqli though, if you’re using PHP 5.5 (make.wordpress.org/core/2014/04/07/mysql-in-wordpress-3-9) and so it’s wise to ALWAYS use the WordPress $wpdb classes for your database access.
How does PDO prevent SQL injection?
PDO provides methods that make parameterized queries easy to use. It also makes the code easier to read and more portable – it works with several databases, not just MySQL. This improved code uses PDO with parameterized queries to prevent the SQL Injection vulnerability.
How does PDO object connect to MySQL database?

Is there support for PDO in SQL Server?
