Remove empty array elements

Question

Some elements in my array are empty strings based on what the user has submitted. I need to remove those elements. I have this:

foreach($linksArray as $link)         


        

Answer 1

I had to do this in order to keep an array value of (string) 0

$url = array_filter($data, function ($value) {
  return (!empty($value) || $value === 0 || $value==='0');
});
