Is there a way in php to remove elements in an array and then reindex the remaining elements? For example, here is what I want to do. In an array, 

$a = array("a","b","c");

I want to delete element "b", I used unset() to do that leaving the array like ("a",null,"c"). What I really want is make the array ("a","c") after deleting "b". How can I do that? Thanks!

unset does not create null elements in your array. The array will be one element smaller than before.

If you want to reindex the array after removing an element, use $array = array_values($array);.

do you want to do something like 

 $new_array = array_filter($a)

? You can read about array filter function and take a look at the case without callback parameter (as in my example)

unset($a[1]);
$a = array_values($a);
