PHP饼图数据格式化

我正在尝试以正确的格式获取flot饼图中的数据。我已经设法得到正确的数据输出，但我需要帮助它得到正确的格式，以便饼图工作。PHP饼图数据格式化

以上

Array 
(
[0] => Array 
    (
     [incident_type] => intoxicated_persons, street_offenses, 
    ) 

[1] => Array 
    (
     [incident_type] => intoxicated_persons, 
    ) 

[2] => Array 
    (
     [incident_type] => information_only, 
    ) 

[3] => Array 
    (
     [incident_type] => information_only, 
    ) 

[4] => Array 
    (
     [incident_type] => information_only, 
    ) 

[5] => Array 
    (
     [incident_type] => information_only, 
    ) 

[6] => Array 
    (
     [incident_type] => brawl, 
    ) 

[7] => Array 
    (
     [incident_type] => intoxicated_persons, 
    ) 

[8] => Array 
    (
     [incident_type] => information_only, 
    ) 

[9] => Array 
    (
     [incident_type] => information_only, 
    ) 

[10] => Array 
    (
     [incident_type] => brawl, 
    ) 

[11] => Array 
    (
     [incident_type] => information_only, 
    ) 

[12] => Array 
    (
     [incident_type] => information_only, 
    ) 

[13] => Array 
    (
     [incident_type] => intoxicated_persons, 
    ) 

[14] => Array 
    (
     [incident_type] => brawl, 
    ) 

[15] => Array 
    (
     [incident_type] => brawl, 
    ) 

[16] => Array 
    (
     [incident_type] => stealing, 
    ) 

[17] => Array 
    (
     [incident_type] => information_only, 
    ) 

[18] => Array 
    (
     [incident_type] => information_only, 
    ) 

[19] => Array 
    (
     [incident_type] => intoxicated_persons, street_offenses, 
    ) 

[20] => Array 
    (
     [incident_type] => information_only, 
    )

相同的数据，和下面我的功能：

public function show_pie_data() 
{ 
    //Use the same data 
    //$all_incident_type = $this->incidents_m->get_all_incident_types(); 

    $result = array(); 
    $final_result = array(); 

    foreach($all_incident_type as $value) 
    { 
     $date_bits = explode(', ', $value['incident_type']); 

     foreach ($date_bits as $key => $value) { 
      if($value != ''){      
       $result[] = $value;     
      }    
     } 
    } 
    //print_r(array_count_values($result)); 

    foreach (array_count_values($result) as $k => $v) { 
     $final_result[] = "{label:". $k .", data:". $v ."}";       
    } 

    // {label:"test",data:10} 

    return json_encode($final_result); 
}

这是我的解决方案：

<?php 

/** 
* @author lolkittens 
* @copyright 2013 
*/ 

$cases = array(
    array(
     'incident_type' => 'brawl' 
    ), 
    array(
     'incident_type' => 'brawl' 
    ), 
    array(
     'incident_type' => 'brawl' 
    ), 
    array(
     'incident_type' => 'brawl' 
    ), 
    array(
     'incident_type' => 'brawl' 
    ), 
    array(
     'incident_type' => 'intoxicated_persons' 
    ), 
    array(
     'incident_type' => 'intoxicated_persons' 
    ), 
    array(
     'incident_type' => 'intoxicated_persons' 
    ), 
    array(
     'incident_type' => 'intoxicated_persons' 
    ), 
    array(
     'incident_type' => 'intoxicated_persons' 
    ), 
); 
$flat = array(); 
$unique = array(); 
$counts = array(); 
$final = array(); 
$json = array(); 
//FILTER THE UNIQUE VALUES 
foreach($cases as $key => $value){ 

    foreach($value as $k => $v){ 

     if(!in_array($v,$unique)){ 
      $unique[] = $v; 
     } 
    } 
} 
// FLATTEN THE ARRAY 
foreach($cases as $key => $value){ 

    foreach($value as $k => $v){ 
     $flat[$key] = $v; 
    } 
} 
// COUNT 
foreach($flat as $key => $val){ 

    if(in_array($val,$unique)){ 
     if(array_key_exists($val,$final)){ 
      $final[$val] = $final[$val] + 1; 
     }else{ 
      $final[$val] = 0; 
     } 
    } 
} 
$count = 0; 
foreach($final as $k => $v){ 
    $json[$count]['label'] = $k; 
    $json[$count]['data'] = $v; 
    $count++; 
} 

echo json_encode($json); 
?>

结果：

[{"label":"brawl","data":4},{"label":"intoxicated_persons","data":4}]

它需要输出这个：{label：“brawl”，data：4}， {[“label”：“brawl”，“data”：4}，{“label”：“intoxicated_persons”，“data”：4}] 注意我不喜欢没有[]和“标签”或“数据” – user1531830
