php - 如何从while循环创建逗号分隔列表？

Question

$personas = [
'Hermann' => [
  'status' => '0',
  'gender' => 'maskulin'
],
'Lida' => [
  'status' => '1',
  'gender' => 'feminin'
],
'Susi' => [
  'status' => '0',
  'gender' => 'feminin'
],
'Mara' => [
  'status' => '0',
  'gender' => 'feminin'
]
];

状态为 0 的角色

  echo 'Personas with status 0: ';
  while ($status = current($personas)) {
    if ($status['status'] == '0') {
    $status_list = key($personas);
    echo $status_list;

  }
  next($personas);
}

结果是： 状态为 0 的角色：HermannSusiMara

预期： 状态为 0 的角色：Hermann、Susi、Mara

为您提供一些不同的解决方案。

$statusZeroPersonae = [];

foreach($personas as $personaName => $persona) {
    if ($persona['status'] === '0') {
        $statusZeroPersonae[] = $personaName;
    }
}

echo 'Personae with status 0: ' . implode(", ", $statusZeroPersonae);
