如何将 ini 文件解析为对象

Question

我正在如下获取 ini 文件的内容

$file = 'config.ini';
if (!file_exists($file)) {
    $file = 'config.sample.ini';
}
$config = parse_ini_file($file, true);

这会产生一个多维数组，但我更希望它是一个对象。 parse_ini_file() 这可能吗？我该怎么做？

Answer 1

如果你想将数组转换为 stdClass，只需使用这个：

$configObj = (object) parse_ini_file($file, true);

Answer 2

您可以使用 json_encode() 和 json_decode() 来实现：

$file = 'config.ini';
if (!file_exists($file)) {
  $file = 'config.sample.ini';
}
$config = parse_ini_file($file, true);
// convert to data to a json string
$config = json_encode($config);
// convert back from json, the second parameter is by
// default false, which will return an object rather than an
// associative array
$config = json_decode($config);

您可以使用其他两种方法将数组更改为对象。



    function array_to_object($array, &$object)
    {
        foreach ($array as $key => $value)  {
            if (is_array($value)) {
                $object->$key = new stdClass();
                array_to_object($value, $object->$key);
            } else {
                $object->$key = $value;
            }
        }

         return $object;
    }

    function arrayToObject($array)
    {
        $object= new stdClass();
        return array_to_object($array, $object);
    }

例子



    $configArr = array(
        'NAME' => 'stack over flow',
        'AGE'  => 28,
        'SEX'  => 'MALE',
    );
    $configObj = arrayToObject($configArr);
    var_dump($configObj);

输出



    class stdClass#1 (3) {
      public $NAME => string(15) "stack over flow"
      public $AGE  => int(28)
      public $SEX  => string(4) "MALE"
    }

如果您对此有一些高级机制，请尝试以下代码示例。
