Array ( [0] => 0 [1] => [2] => 3 [3] => )

i want to remove null values from this and the result should be like this

Array ( [0] => 0 [1] => 3) i don't want to remove 0 value from array.

You can use array_filter() which will get rid of the null empty values from the array

print_r(array_filter($arr, 'strlen'));
