Question

以下是带有stdClass对象的数组

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

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

我希望获得与Content

对应的Number的价值

例如。对于数字5，获取值00666

提前感谢。

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
}

调用这样的函数：

echo returnContent($objArray, 5);

或将其分配给变量：

$content = returnContent($objArray, 5);

请务必检查号码是否存在：

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

Answer 2

您可以为此创建一个功能：

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

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`
