Please expalin the use of this function

[apysan]

Hello friends, I have just begun to learn PHP. I prefer to learn in PDO way.

I write the following code to connect to phpmyadmin (wamp).

unable to understand the use of this function, even if it is useful why do we mention only two parameter with this, please help to

understand.

try{

$handler = new PDO('mysql:host=localhost;dbname=arjun_kaa_database','root','');

$handler->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

}

catch(PDOException $e)

{

//echo "An Error is Catched<br>"; //$e->getmessage();

//die("More Specific Message will be >--------------> Something Wrong with the Database");

echo $e->getMessage();

die();

}

Thanks and Regards

What that line is doing is telling PDO to throw an exception if a MySQL error occurrs. This would mean you can catch MySQL errors using a try-catch block.

 

For example:

try {    // .. Some PDO database operations} catch(PDOException $e) {    echo 'MySQL error: ' . $e->getMessage();}

PDO's setAttribute() method just sets some of PDO's configuration.

The manual lists some of the attributes that you can set:http://php.net/manual/en/pdo.setattribute.php
