' Utf-8 ': ' GBK ');    Split the incoming string into an array, mainly for the following code to write up a convenient point $t = Array (); for ($i =0; $i
  
   
     = count ($a)) break;            }elseif ($k) break;                    }//Check matching case if ($n-$i > 1) {if ($buf) {$r [] = $buf;                $buf = ";                } $r [] = Join ("', Array_slice ($a, $i, $n-$i));            $i = $n;        }else $buf. = $a [$i + +];        if ($BUF) $r [] = $buf; List ($b, $a) = Array ($a, $b);    Swap two sets of data, and again}while ($loop-); 
 Return Array_count_values ($R);}
