Written by Ian Carnaghan · 13 sec read >
  1. 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>';
    
  2. The result will be only the NOT NULL values
    Array
    (
        [1] => 1
        [3] => 3
    )
