How to remove null or empty values from an array in PHP
In this tutorial, we are going to see how to remove null or empty values from an array in PHP. You can use the PHP array_filter() function to remove or filter empty values from an array.

However, if no callback is specified, all values in the array equal to FALSE will be removed, such as an empty string or a NULL value.
