delete null values from an array in php

Question

I have an array in php $arr("ABC","","XYZ","",""). now i want to trim the null values in the array and want $arr("ABC","XYZ"). And the element number must also be manipulated likewise which means "XYZ" must have the key value as 1 after trimming. How do we do it? Thanks in advance! Cheers!

Note that those aren't null values that you're removing, they're empty strings — Mark Baker

Use array_filter()

Filters elements of an array using a callback function. If no callback is supplied, all entries of array equal to FALSE (see converting to boolean) will be removed.

$arr = array_filter($arr);
