Question

I started learning PDO and im still a bit of a PHP novice. Im doing a project to increase my knowledge but im stuck at the first hurdle.

Im getting this error: Call to a

Answer 1

Get same error and couldn't fix with code written above.

Here is easy fix as in your code this is the problem why PDO Sending Error :

public function __construct(){
    // Set DSN
    $dsn = 'mysql:host=' . $this->host . ';dbname=' . $this->dbname;
    // Set options
    $options = array(
        PDO::ATTR_PERSISTENT    => true,
        PDO::ATTR_ERRMODE       => PDO::ERRMODE_EXCEPTION
    );
    // Create a new PDO instanace
    try{
        $this->dbh = new PDO($dsn, $this->user, $this->pass, $options);
    }
    // Catch any errors
    catch(PDOException $e){
        $this->error = $e->getMessage();
    }
}

I am using PHP 5.5 and if someone have same error then he will need this

After $dns you need to add this where $this->dbname . ";";

Only this is how it will work for PHP 5.5 and Will not work with $this->dbname . "'";

public function __construct(){
    // Set DSN
    $dsn = 'mysql:host=' . $this->host . ';dbname=' . $this->dbname . ";";
    // Set options
    $options = array(
        PDO::ATTR_PERSISTENT    => true,
        PDO::ATTR_ERRMODE       => PDO::ERRMODE_EXCEPTION
    );
    // Create a new PDO instanace
    try{
        $this->dbh = new PDO($dsn, $this->user, $this->pass, $options);
    }
    // Catch any errors
    catch(PDOException $e){
        $this->error = $e->getMessage();
    }
}
