How to output a different value if $row is empty?

Question

PHP

Hello, I'm so-so in PHP .., so the question is:
There is a code that takes a value in the database from the "link" field.

$tpl->set("{вывод-тега}",stripslashes($row['ссылка']));

So, if the field "link" in the database is empty, is it possible to draw another field "link 2"?

Answer 1

$value = array_key_exists('ссылка', $row) ? $row['ссылка'] : $row['ссылка2'];
$tpl->set("{вывод-тега}",stripslashes($value));
