this code seems to be alright, problem will be in other part of code – Marek Janoud
Please paste the code around this line. This line seems to be fine, so the issue must be on the line before or after. – Scalpweb

If you are using a version of PHP older than 5.5, you can only use variables within empty, and not method calls, otherwise it will throw the error you have received.

A solution would be to calculate the return value first, for example:

$links = $this->config->get('refprogram_sharing_links');

if ($this->config->get('refprogram_sharing_enable') && !empty($links)) {

Depending on the output of your get method, you could also try

&& $this->config->get('refprogram_sharing_links') !== false

Hard to tell if this would work without seeing the rest of your code, though.

In case if the first variable is string and the second is array:

$refprogram_sharing_enable = $this->config->get('refprogram_sharing_enable');
$refprogram_sharing_links = $this->config->get('refprogram_sharing_links');

if ( $refprogram_sharing_enable!='' && !empty($refprogram_sharing_links)) {

}
