Question

我正在建立一个流程图（非常类似于Sankey图），但我的数据有些问题。

我从API调用中获取了一个JSON文件。我正在使用PHP脚本将JSON输出存储在MySQL数据库中。

问题在于现在的布局：

('A, B, C, D, E, F', 123456),
('A, B, C, D', 6543),
('B, C', 94934),

我需要什么（我想分开每一步，但需要每一步的值来创建te流程图）。

('A, B', 123456),
('B, C', 123456),
('C, D', 123456),
('D, E', 123456),
('E, F', 123456),
('A, B', 6543),
('B, C', 6543),
('C, D', 6543),
('B, C', 94934)

JSON to Database

$json_data = file_get_contents($CALL);
$json_data = str_replace("'","",$json_data);
$array = json_decode($json_data,true);
$sql_inserts = array();
foreach($array['reportitems']['reportitem'][0]['rows']['r'] AS $row)
    {
        $sql_inserts[] = "('".$row[c][0]."','".$row[c][1]."')";
    };
$sql = 'INSERT INTO flow (flow,number) VALUES '.implode(",",$sql_inserts);
    if (mysqli_query($conn, $sql)) {
            echo "Ok";
    } else {echo "<Error" . mysqli_error($conn) ;}
mysqli_close($conn);

输出API调用 - JSON

    "@count": "1",
    "reportitem": [

            },
            {
              "ctitle": "number",
              "type": "integer",
              "alignment": "right"
            }
          ]
        },
        "title": "flow",
        "statistics": {
          "total": {
            "c": [
              "",
              "10813438"
            ]
          },
          "maximum": {
            "c": [
              "",
              "2482782"
            ]
          },
          "average": {
            "c": [
              "",
              "29"
            ]
          },
          "minimum": {
            "c": [
              "",
              "1"
            ]
          }
        },
        "rows": {
          "@count": "3",
          "r": [
            {
              "c": [
                "A, B, C, D, E, F",
                "123456"
              ]
            },
            {
              "c": [
                "A, B, C, D",
                "6543"
              ]
            },
            {
              "c": [
                "B, C",
                "94934"
              ]
            }
          ]
        }
      }
    ]
  }
}

我需要在哪里解决这个问题？将JSON输出写入MySQL数据库的脚本？或者从数据库到sankey图的查询（期望分离的格式）？

您可以尝试：

foreach($array['reportitems']['reportitem'][0]['rows']['r'] AS $row)
{
    // EXPLODE TO GET INDIVIDUAL CHARACTERS
    $explodedCharac = explode(',', $row[c][0]);
    // LOOP THROUGH EACH CHARACTER
    foreach($explodedCharac as $key => $charac) 
    {
        // CHECK IF THIS IS NOT THE LAST CHARACTERS IN THE EXPLODED LIST
        if(isset($explodedCharac[$key+1])) {
             // PREPARE ARRAY WITH CURRENT AND NEXT CHARACTER, IF THIS IS NOT THE LAST CHARACTER IN THE EXPLODED LIST
             $sql_inserts[] = "('".$explodedCharac[$key].", ".$explodedCharac[$key+1]."','".$row[c][1]."')";
        }
    }

};

逗号分隔步骤，一个值到多个步骤，具有相同的值
