Remove empty array elements
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 $link)
{
if($link == '')
{
unset($link);
}
}
print_r($linksArray);
But it doesn't work. $linksArray still has empty elements. I have also tried doing it with the empty() function, but the outcome is the same.
