Php 将JSON数据保存到一行中

大家早上好

我很难想出如何安排以下JSON：

{
   "showElement": "1",
   "degrees": [{
       "Name": "Bachelor in Psychology",
       "Number": "53",
       "degree": "Bachelor's Degree"
   }, {
       "Name": "Certificate",
       "Number": "56",
       "degree": "Certificate"
   }, {
       "Name": "High School Diploma",
       "Number": "28",
       "degree": "High School"
   }, {
       "Name": "Bachelor in Sociology",
       "Number": "109",
       "degree": "Bachelor's Degree"
   }]
}

为此：

{
   "showElement": "1",
   "degrees": [{
       "Name": "Bachelor in Psychology", "Bachelor in Sociology",
       "Number": "53","109",
       "degree": "Bachelor's Degree"
   }, {
       "Name": "Certificate",
       "Number": "56",
       "degree": "Certificate"
   }, {
       "Name": "High School Diploma",
       "Number": "28",
       "degree": "High School"
   }]
}

基本上，将相同的学位放在一个地方，并用逗号分隔所述学位的所有名称

我已经将此JSON解码为一个变量：

$data = json_decode($topDegrees[1]["diplomas"],true);

提前感谢您的帮助

我想到了这个

$json = <<<JSON
{
   "showElement": "1",
   "degrees": [{
       "Name": "Bachelor in Psychology",
       "Number": "53",
       "degree": "Bachelor's Degree"
   }, {
       "Name": "Certificate",
       "Number": "56",
       "degree": "Certificate"
   }, {
       "Name": "High School Diploma",
       "Number": "28",
       "degree": "High School"
   }, {
       "Name": "Bachelor in Sociology",
       "Number": "109",
       "degree": "Bachelor's Degree"
   }]
}
JSON;

$data = json_decode( $json, true );

$degrees = $data['degrees'];
$names = array_column($degrees, 'degree');
$count = array_count_values($names);
$duplicates = array_filter($count, function($var) {
  return $var > 1;
});


foreach ( array_flip($duplicates) as $degree ) {

  $filter = array_filter($degrees, function($var) use ($degree) {
    return ( $var['degree'] === $degree );
  });

  $names = [];
  $numers = [];
  foreach ( $filter as $item ) {
    $names[] = $item['Name'];
    $numbers[] = $item['Number'];
  }
  $indices = array_keys($filter);
  $index = array_shift($indices);
  $degrees[$index]['Name'] = $names; // = join(', ', $names);
  $degrees[$index]['Number'] = $numbers; // = join(', ', $numbers);

  while ( count($indices) ) {
    unset($degrees[array_shift($indices)]);
  }
}

$data['degrees'] = $degrees;

print_r(json_encode($data));
// {"showElement":"1","degrees":[{"Name":["Bachelor in Psychology","Bachelor in Sociology"],"Number":["53","109"],"degree":"Bachelor's Degree"},{"Name":"Certificate","Number":"56","degree":"Certificate"},{"Name":"High School Diploma","Number":"28","degree":"High School"}]}

$json=
$str=>{
“showElement”：“1”，
“学位”：[{
“姓名”：“心理学学士”，
“编号”：“53”，
“学位”：“学士学位”
}, {
“名称”：“证书”，
“编号”：“56”，
“学位”：“证书”
}, {
“姓名”：“高中文凭”，
“编号”：“28”，
“学位”：“高中”
}, {
“姓名”：“社会学学士”，
“编号”：“109”，
“学位”：“学士学位”
}]
}';
$str_arr=json_decode（$str）；
foreach（$str_arr->degrees as$k=>$val）{
如果（$val->degree==‘学士学位’）{
$new['bacher'][=$val；
}否则{
$new[]=$val；
}
}
foreach（$new['bacher']作为$aa）{
$nameStr[]=$aa->Name；
$numStr[]=$aa->Number；
}
$nameStr=内爆（“，”，$nameStr）；
$numStr=内爆（“，”，$numStr）；
$学位='学士学位'；
$new[]=（对象）数组（$nameStr、$numStr、$degree）；
unset（$new[‘学士’]）；
echo$json=json_encode（$new）；
回声“；打印（json解码（$json））；

希望这有帮助

这应该可以做到：

你为什么要这么做，因为JSON是无效的..这在@glaux中非常有效，非常感谢！
