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

If you are working with a numerical array and need to re-index the array after removing empty elements, use the array_values function:

array_values(array_filter($array));
