This PDO prepared statement returns false but does not throw an error

Question

This code does not throw an error but the query fails, that is, the execute method returns false. How could that be?

require_once(\"Abstracts/DBMana         


        

Answer 1

It also happens when you use PDOStatement::bindValue() with PDO::PARAM_BOOL. Solution: just switch to PDO::PARAM_INT.
