如何使用stdClass對象解析PHP數組

Question

以下是帶有stdClass對象的數組

Array
(
    [0] => stdClass Object
        (
            [Number] => 5
            [Content] => 00666
        )

    [1] => stdClass Object
        (
            [Number] => 7
            [Content] => 1018456550591052212900797790669502
        )
)

我希望獲得與Number對應的Content值

例如。 對於5獲得值00666

預先感謝。

Answer 1

添加此功能：

function returnContent($myObjectArray, $number)
{
   foreach($myObjectArray as $obj){
      if ($obj->Number == $number)
         return $obj->Content;
      }
   }
   return "number not in array"; //or some other value to denote an error
}

調用這樣的函數：

echo returnContent($objArray, 5);

或將其分配給變量：

$content = returnContent($objArray, 5);

請務必檢查號碼是否存在：

if ($content != "number not in array"){ //or whatever value you assigned to denote a failure
   //do something
}

Answer 2

你可以為此創建一個函數：

function getContent($needle, $haystack) {
  foreach($haystack as $v) if($needle==$v->Number) return $v->Content;
  return null;
}

要使用它：

$result = getContent(5, $myArray);
if($result===null) die('Value not found.');
// Use result however you want now

Answer 3

$myObjectArray= myObjectArray() // array of objects

foreach($myObjectArray as $val) {
    echo $val->Content;
}

It will print `00666` and `1018456550591052212900797790669502`
