How to re-index an array after calling unset()? [duplicate]

Question

I have an array in php like:

$a = array(0=>'a', 1=>'b', 2=>'c', 3=>'d');

Now I unset an element in array:

unset($a[2]);

Now I have the array as:

$a = array(0=>'a', 1=>'b', 3=>'d');

But I want to reorder the array such that the indexes are numerically organized, like:

$a = array(0=>'a', 1=>'b', 2=>'d');

What I can do to get this change?

this should do it:

$new_array = array_values($old_array);

A solution is to merge your array with an empty array, like so:

$a = array_merge(array(), $a);
