How to use foreach value for db coumn name as variable in Codeigniter view file

Question

I have a view file where I need to echo db column values using foreach method.

I have column e.g. column_a, column_b, column_c....

I am able to get values if I use <?= $variable_1->column_a; ?>

But I need to echo them like <?= $variable_1->column_.$variable_2; ?>

If I use it the second way, gives error

Message: Undefined property: stdClass::$column_

Try

<?php $colname = "column_{$variable_2}"; ?>
<?= $variable_1->{$colname}; ?>

Thanks @Alan Horrocks.. It still says, `UNDEFINED column_{$column}` – CodeIgniter_Learner Feb 15 '16 at 22:32
Glad you got it working :) Note that using double-quotes was important in my answer - if you use single quotes php won't interpret the value of $column. – Alan Horrocks Feb 15 '16 at 22:45

Thanks for @Alan Horrocks as he showed me the right direction:

I worked by doing

<?php $column = $session_data['default']; ?> <?php $colname = 'column_'.$column; ?> <?= $listing->$colname; ?>
