"delete $hash{$key}" in loop deletes only the only one time - why

"delete $hash{$key}" in loop deletes only the only one time - why

here is the idea:
I want to delete   the keys and values from a hash
( the keys are elements of an array)
and when i use this code- it runs and deletes only the first element of the hash
here is the code

sub del_elementt{
@array=split /,/,$art;

open (TEMP, "/temp.txt")¦¦&error;
close (TEMP);
foreach $f(@a_file){
  @arr=split '=',$f;
foreach $key(@array){
delete $my_hash{$key};

and it tells me that only the first element is deleted
when i try to use the exists funtion it tells me that only
the first element exist
but when i put the second element first it is deleted

help pls
i spend  2 days and a night
about solving this problem  
 thank you
