PHP PDO class programming:Fatal error: Call to a member function fetchAll() on boolean

Question

I am new to the class programming in php ,Here is my database class.

class Database
{
    private $_connection;
    private static $_instance; //The single insta         


        

Answer 1

You need to return the $result only in the run() method:

public function run($sql)
    {
        $result=$this->_connection->prepare($sql);
        $result->execute();
        return $result;
    }

Returning the $result->execute(); is returning true because the execute() succeeded. You need to return the current state of $result.

See if that works.
