If you have an array with empty values and you wish to remove the empty valuesyou can use the following one line code

		$array = array('','1','','3');
 
		$array = array_filter($array, 'strlen');
 
		echo '<pre>';
 
		print_r($array);
 
		echo '</pre>';

The result will be only the NOT NULL values
```
Array
(
    [1] => 1
    [3] => 3
)
```
