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– Scalpweb2016-10-01 14:05:53 +00:00Commented Oct 1, 2016 at 14:05

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)) {
}
