array_diff

Hi all, I am getting some weird results when using the array_diff() function. eg: $arrayResult = array_diff($array1, $array2); When i use it the resulting array ($arrayResult) gets the correct number of elements, however when I echo the elements in $arrayResult it contains some blank values. eg: $array1 = [123] [120] [44] [54] $array2 = [120] [54] then when I display $arrayResult: [123] ... -> blank value which should be 44. According to the manual : "Array_diff() returns an array containing all the values of array1 that are not present in any of the other arguments" it should return [123] and [44]. What is the reason for it being blank??
