In a PHP script, you have a PDO prepared statement that updates user information based on user ID. However, sometimes the script fails silently without any error. Which of the following could be a method to diagnose the issue?

  • Enable PDO error mode
  • Add more SQL queries for error handling
  • Increase the PHP memory limit
  • Use unprepared SQL queries
Enabling PDO error mode will help identify errors in your SQL statements and provide detailed error messages, aiding in issue diagnosis.
