hello :
  i have a problem on remove 2 dimension array in which the count of array still is same as before the array was remove.

example:
  $e[0][0] = "aaa";
  $e[0][1] = "bbb";
  $e[1][0] = "111";
  $e[1][1] = "222";
  
  count(array) is equal to 2, then i try to remove an element of that array using unset :
  unset($e[1][0]);
  unset($e[1][1]);

 then i try to retrieve the count of array again, the result should be 1, but what i get from it is the count of the array is still not change, which it :
  echo count($e);    //result is 2

i have been try this for single dimension array, there is no such problem on it, just the 2 dimension array will face this kind of problem.

thank you !!

In your sample you removed 2nd dimensions from $e, not 
first, so $e[1] is an empty array.

e.g. vardump($e):
array(2) { [0]=> array(2) { [0]=> string(3) "aaa" [1]=> 
string(3) "bbb" } [1]=> array(0) { } }

To remove first dimension use unset($e[1])

Regards

Georg
