遍历由关联数组组成的数组

Question

我有一个如下所示的数组：

[

   {
    "positional_index":"1.3",
    "sourceid":10409,
    "language": "Malayalam",
    "field_gita_10409_text": "Behold, O Teacher! this mighty army of the sons of Pandu, arrayed by the son of Drupada, thy wise disciple."


   },

   {
    "positional_index":"1.2",
    "sourceid":10409,
    "language": "Devanagari",
    "field_gita_10409_text": "1.1 Dhritarashtra said What did my people and the sons of Pandu do when they had assembled together eager for battle on the holy plain of Kurukshetra, O Sanjaya."



   },
]

我应该使用 foreach 循环来访问每个键。例如，如果键 = field_gita_10409_text，我必须使用 php 中的 explode() 函数来提取值 10409 等

我不知道在这种情况下如何使用 foreach 循环，因为该数组包含 2 个关联数组。请告诉我。

Answer 1

循环内循环：

foreach ($array as $item){
        foreach ($item as $key=>$value){
            //do stuff
        }
    }

Answer 2

您需要内部循环来获取键和值。

$array = json_decode($json);

foreach ($array as $innerArray){
        foreach ($innerArray as $key=>$value){
            if($key == 'field_gita_10409_text'){
              $exp = explode($value);
            }
        }
    }
