私は現在、私のウェブサイトhttp://codemink.comでバイナリツリーをウェブ上に表示することで構成される、ある種の情報の視覚化に取り組んでいます

このために、私はこのライブラリを使用しています: http://philogb.github.io/jit/static/v20/Jit/Examples/Spacetree/example2.html

これは、上記の例のメイン コード構造です。

//init data

//A client-side tree generator
var getTree = (function() {
    var i = 0;
    return function(nodeId, level) {
      var subtree = eval('(' + json.replace(/id:\"([a-zA-Z0-9]+)\"/g, 
      function(all, match) {
        return "id:\"" + match + "_" + i + "\""  
      }) + ')');
      $jit.json.prune(subtree, level); i++;
      return {
          'id': nodeId,
          'children': subtree.children
      };
    };
})();

問題はJSONです。AJAXを使用してPHPからこのJSONデータを取り込もうとしています。これは私がPHPでやろうとしていることです:

<?php
$json = '{
"aaa":1,
"b":2,
"c":3,
"d":4,
"e":5,
"fff":{"a":11111,"b":222222,"c":33333,"d":444454,"e":55555555},
"last":[
      {
        id: 8817,
        name: "NEW YORK CITY"
      },
      {
        id: 2873,
        name: "UNITED STATES"
      },
      {
        id: 1501,
        "loc": "NEW YORK STATE"
      }
    ]
}';


$php = json_decode($json, true);
echo var_export($php);

?>

それは機能していません。助けてください。！

json_encodeとjson_decode例

あなたは$json正しいJSON文字列を持っています - PHPによって作られました

<?php

$data = array(
    "aaa" => 1,
    "b" => 2,
    "c" => 3,
    "d" => 4,
    "e" => 5,
    "fff" => array(
        "a" => 11111,
        "b" => 222222,
        "c" => 33333,
        "d" => 444454,
        "e" => 55555555
    ),
    "last" => array(
      array(
        "id" =>  8817,
        "name" =>  "NEW YORK CITY"
      ),
      array(
        "id" =>  2873,
        "name" =>  "UNITED STATES"
      ),
      array(
        "id" =>  1501,
        "loc" =>  "NEW YORK STATE"
      )
    )
);


$json = json_encode($data);
echo '<pre>', $json ,'</pre>';

$data_again = json_decode($json, true);
echo '<pre>', print_r($data_again) ,'</pre>';

?>
