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 $link) { if($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.

In PHP you have a built in function to what are you trying to achieve. You can use this function array_filter()

Here is an example:

$array = ["apple", "", null, "banana", 0, "0", [], "cherry"];

$clean = array_filter($array);

print_r($clean);

This function will remove "", null, 0, "0", and false.
