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. This function usually filters the values of an array using a callback function. 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.
