Question

I am using Yii for my web application. In this I kept Constants class in model and extended

from CUserIdentity like..

class Constants extends CUserIdentity
{
 CONST ACCOUTN_ONE = 1;
 CONST ACCOUTN_TWO = 2;
 CONST ACCOUTN_THREE = 3;
}

Here I can access constants like Constants::ACCOUTN_ONE and it will return correct result as 1

But when I start construct constants dynamically means..

$type = 'ONE';
$con = "Constants::ACCOUTN_".$type;
echo $con;

It will dispaly as Constants::ACCOUTN_ONE;

I am expecting here 1

Please correct me if any mistake..

Answer 1

$type = 'ONE'; // You created string

$con = "Constants::ACCOUTN_".$type; // Created other string

echo $con; // Printed it

You just printed string without evaluating it.
Yes, of couse it will dispaly as Constants::ACCOUTN_ONE;

You need to evaluate your code with eval()(bad), or use this scheme:

echo Constant($con);
