如何解决多维数组中的问题

Question

我有一个多维数组，如下所示。我想循环显示内容，所以我正在使用 foreach 循环，但出现错误

**Notice: Undefined index: propertyId in C:\xampp\htdocs**

我该如何解决这个问题？

$proprty_id=
Array
(
    [propertyId] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
            [3] => 4
        )

    [ProprtyName] => Array
        (
            [0] => Residential Project 1 
            [1] => Residential Project 2
            [2] => Residential Property 3
            [3] => Residential Property 4
        )

)
foreach($proprty_id as $property){
    echo "ID = ".$property['propertyId']."<br>";
}

您将数组定义为 $proprty_id 并将其命名为 $property 也许还有一些错别字？

你的循环没有检查你的数组内部，因为它有不同的名字。

$property=array(
    ['propertyId'] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
            [3] => 4
        )

    ['ProprtyName'] => Array
        (
            [0] => Residential Project 1 
            [1] => Residential Project 2
            [2] => Residential Property 3
            [3] => Residential Property 4
        )

)
               foreach($property['propertyId'] as $v){

                    echo "ID = ".$v."<br>";
                }
