So in PDO, your options are:
  • Use MySQL's FOUND_ROWS() function.
  • Use PDO's fetchAll() function to fetch all the rows into an array, then use count() on it.
  • Do an extra query to SELECT COUNT(*) , as karim79 suggested.

    • Furthermore, how do I check the number of rows in PDO?

    PDO doesn't have a magic method that counts the number of rows returned from a SELECT call. You can use the PDOStatement->rowCount method to return the number of rows returned by a SELECT statement with some PDO database drivers.
