得到与json_decode

Question

JSON数组我有一个JSON文件是这样的：

[{"id":"PMC102324", 
"Original_paper":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC102324/pdf", 
"Annotated_file":"http://nactem10.mib.man.ac.uk/brat-v1.3/#/NCSTOX/PMC102324", 
"Title":"Glucosinolate breakdown products as insect fumigants and their effect on carbon dioxide emission of insects", 
"Molecule":[{"Main name":"glucosinolate", "Synonyms":[]},{"Mainame":"isothiocyanate", "Synonyms":[]},{"Main name":"hexane", "Synonyms": []},{"Main name":"sinigrin", "Synonyms":[]},{"Main name":"allyl glucosinolate", "Synonyms":[]},{"Main name":"rotenone", "Synonyms":[]},{"Main name":"sucrose", "Synonyms":[]},{"Main name":"thiocyanate", "Synonyms":[]},{"Main name":"allyl isothiocyanate", "Synonyms":[]}], 
"ToxKeywords":"safety, cytotoxic, ", 
"Important_sentences":["The mode of action of many isothiocyanate compounds has also been attributed to their capability for alkylating the nucleophilic groups of biopolymers such as DNA, thus having cytotoxic properties which can affect the formation of the spiracular epidermis and crochet on the prolegs of tobacco hornworm (Manduca sexta L.) caterpillars [28-30]."] 
}] 

当我使用json_decode的var_dump()回报：

array (size=1) 
0 => 
array (size=7) 
    'id' => string 'PMC102324' (length=9) 
    'Original_paper' => string 'https://www.ncbi.nlm.nih.gov/pmc/articles/PMC102324/pdf' (length=55) 
    'Annotated_file' => string 'http://nactem10.mib.man.ac.uk/brat-v1.3/#/NCSTOX/PMC102324' (length=58) 
    'Title' => string 'Glucosinolate breakdown products as insect fumigants and their effect on carbon dioxide emission of insects' (length=107) 
    'Molecule' => 
    array (size=9) 
     0 => 
     array (size=2) 
      ... 
     1 => 
     array (size=2) 
      ... 
     2 => 
     array (size=2) 
      ... 
     3 => 
     array (size=2) 
      ... 
     4 => 
     array (size=2) 
      ... 
     5 => 
     array (size=2) 
      ... 
     6 => 
     array (size=2) 
      ... 
     7 => 
     array (size=2) 
      ... 
     8 => 
     array (size=2) 
      ... 
    'ToxKeywords' => string 'safety, cytotoxic, ' (length=19) 
    'Important_sentences' => 
    array (size=1) 
     0 => string 'The mode of action of many isothiocyanate compounds has also been attributed to their capability for alkylating the nucleophilic groups of biopolymers such as DNA, thus having cytotoxic properties which can affect the formation of the spiracular epidermis and crochet on the prolegs of tobacco hornworm (Manduca sexta L.) caterpillars [28-30].' (length=343) 

我的目标是获得什么在 '分子'= >阵列

CONTROLER：

/** 
* @Route("/parse_file", name="parseFile") 
* @method("GET") 
*/ 
public function parseFile() 
{ 
    $em = $this->getDoctrine()->getManager(); 
    $em->getRepository('NcstoxBundle:JsonTextMining'); 

    set_include_path('/home/landreau/workspace/NCSTOX/web/assets/json/sample-json'); 
    $json = file_get_contents('PMC102324.json', FILE_USE_INCLUDE_PATH); 
    $tab = json_decode($json, true); 

    var_dump($json); 
    var_dump($tab); 

    foreach ($tab as $item) { 
     $jsonTextMining = new JsonTextMining(); 
     $jsonTextMining->setSolrId($item['id']); 
     $jsonTextMining->setOriginalPaper($item['Original_paper']); 
     $jsonTextMining->setAnnotatedFile($item['Annotated_file'][0]); 
     $jsonTextMining->setTitle($item['Title'][0]); 
     $jsonTextMining->setMolecule($item['Molecule']['Main name']); 
     $jsonTextMining->setMolecule($item['Molecule']['Synonyms']); 
     $jsonTextMining->setKeyword($item['ToxKeywords'][0]); 
     $jsonTextMining->setImportantSentence($item['Important_sentences'][0]); 


     $em = $this->getDoctrine()->getManager(); 
     $em->persist($jsonTextMining); 
    } 

    $em->flush(); 


    return new Response('Saved new document with id ' . $jsonTextMining->getSolrId()); 
} 

它适用于所有项目$为exept分子，我想：

  $jsonTextMining->setMolecule($item['Molecule']['Main name'][0]); 

和其他方式，你认为有办法让这个JSON数组什么或者我应该重新格式化JSON？

Answer 1

试试这个：

$result = json_decode($json, true); 

如果使用true作为第二个参数，json_decode创建关联数组

对于分子可以让这个：

$item['Molecule'][0]['Main name'] 

或本：

$item[0]['Molecule'][0]['Main name'] 

你有很多分子，所以我认为你需要很多插入

Answer 2

试试这个解码的JSON与json_decode($json, true)数组：

<?php 
    $json = '[{"id":"PMC102324", 
    "Original_paper":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC102324/pdf", 
    "Annotated_file":"http://nactem10.mib.man.ac.uk/brat-v1.3/#/NCSTOX/PMC102324", 
    "Title":"Glucosinolate breakdown products as insect fumigants and their effect on carbon dioxide emission of insects", 
    "Molecule":[{"Main name":"glucosinolate", "Synonyms":[]},{"Mainame":"isothiocyanate", "Synonyms":[]},{"Main name":"hexane", "Synonyms": []},{"Main name":"sinigrin", "Synonyms":[]},{"Main name":"allyl glucosinolate", "Synonyms":[]},{"Main name":"rotenone", "Synonyms":[]},{"Main name":"sucrose", "Synonyms":[]},{"Main name":"thiocyanate", "Synonyms":[]},{"Main name":"allyl isothiocyanate", "Synonyms":[]}], 
    "ToxKeywords":"safety, cytotoxic, ", 
    "Important_sentences":["The mode of action of many isothiocyanate compounds has also been attributed to their capability for alkylating the nucleophilic groups of biopolymers such as DNA, thus having cytotoxic properties which can affect the formation of the spiracular epidermis and crochet on the prolegs of tobacco hornworm (Manduca sexta L.) caterpillars [28-30]."] 
    }]'; 
    $array = json_decode($json, true); 
    echo "<pre>"; 
    print_r($array[0]["Molecule"]); 

Answer 3

我不能因为我的名气评论（如果我可以，我。会因为亚历山德罗Minoccheri答案似乎是很好的）

我做了什么亚历山德罗没有和它的工作对我来说：

$res = json_decode($json, true); 
print_r($res[0]['Molecule']); 

给我：

Array 
(
    [0] => Array 
     (
      [Main name] => glucosinolate 
      [Synonyms] => Array 
       (
       ) 

     ) 

    [1] => Array 
     (
      [Mainame] => isothiocyanate 
      [Synonyms] => Array 
       (
       ) 

     ) 
... 

是不是你想要的？如果你想要每个主名，我认为你需要做一个foreach。
