      },
      {         "name": "Scarface",
         "category": "public figure"         
      },
      {         "name": "Johnny Depp",
         "category": "Actor/director"         
      },
      {
         "name": "Once Upon a Time in the West",
         "category": "public figure"         
      },
      {         "name": "Legend of the Guardians: The Owls of Ga'Hoole",
         "category": "public figure"         
      },
      {         "name": "Once Upon a Time in America",
         "category": "public figure"       
      },
      {         "name": "Butch Cassidy and the Sundance Kid",
         "category": "public figure"
        },
      {         "name": "Fracture",
         "category": "public figure"
              },
      {         "name": "Invictus",
         "category": "public figure"

      },
      { "name": "Pride and Glory",
         "category": "public figure"
      }
   ]
}

that i just want the categories count ie ，我只希望类别计数，即

[Movies]=>5 [Tv show]=>4 etc

i used this code

 function array_icount_values($array) { \n    $ret_ar=array(); \n    foreach($array['data'] as $key=>$val) \n    { \n        print_r(array_count_values($val)); \n     }} \n$string = file_get_contents("likes.json"); \n$json_a=json_decode($string,true); \n$re=array_icount_values($json_a);  

But this give strange result.

The text you have there is a JSON. Just decode it an use the same method to count categories as in the function you previously provided. Check this out: http://www.php.net/manual/en/function.json-decode.php

Hope I could help, all the best...

LE:

$arr=json_decode($str);
foreach($arr['data'] as $value){
    $categCount[$value['category']]++;
}

var_dump($categCount);// should give you the categories count
