// One liner to remove empty ("" empty string) elements from your array.
// Note: This code deliberately keeps null, 0 and false elements.
$array = array_filter($array, function($a) {return $a !== "";});

// OR if you want to trim your array elements first:
// Note: This code also removes null and false elements.
$array = array_filter($array, function($a) {

$colors = array("red","","blue",NULL);

$colorsNoEmptyOrNull = array_filter($colors, function($v){
