Question

我正在尝试遍历此数组，来自数据库并将Field_Name和Field_Value输出到网页。

Array
(
    [0] => stdClass Object
        (
            [Field_Name] => First Name
            [Field_Value] => søren
        )

    [1] => stdClass Object
        (
            [Field_Name] => Last Name
            [Field_Value] => hansen
        )

    [2] => stdClass Object
        (
            [Field_Name] => Email
            [Field_Value] => s.hansen@hansens.dk
        )

    [3] => stdClass Object
        (
            [Field_Name] => medlem
            [Field_Value] => ja
        )

    [4] => stdClass Object
        (
            [Field_Name] => Profilbillede
            [Field_Value] => sCZ
        )

    [5] => stdClass Object
        (
            [Field_Name] => bestyrelse
            [Field_Value] => nej
        )

)

如果我使用：

$count=0;
while ($count < 6) {
    $newdata = $data[$count];
    foreach ($newdata as $key => $val) {
        echo "<div class='list'>" . $key . " = " . $val . "</div><br><br>";
    }
$count++;
}

我明白了：

Field_Name = First Name



Field_Value = søren



Field_Name = Last Name



Field_Value = hansen

依旧......

但我需要摆脱Field_Name和Field_Value，以便数组看起来像：

First Name: Søren

Last Name: Hansen

我尝试使用$data[0]["Field_name"]，但它不起作用。我现在疯了，所以我需要朝着正确的方向努力。

我希望我已经说清楚我需要做什么。

Answer 1

辅助尺寸不是数组，它们是对象！所以你不能那样访问它们。

简而言之，您应该可以执行类似$ data [0] - ＆gt; Field_name的操作或者将它们转换为数组然后$ data [0] [“Field_name”]，会起作用！

Answer 2

我认为你正在寻找类似......

的东西

//assuming you have data stored in $data..
$newdata = array();
foreach ($data as $object){

    if ($object->Field_Name && $object->Field_Value){

       $newData[$object->Field_Name] = $object->Field_Value;

    }      

}

Answer 3

为此更改你的foreach：

$count=0;
while ($count < 6) {
    $newdata = $data[$count];
    echo "<div class='list'>" . $newdata["Field_Name"] . " = " . $newdata["Field_Value"] . "</div>   <br><br>";
    $count++;
}
