将数组中的数组值存储到PHP变量中

我使用XML解析器将XML提要数据存储到mysql表中，如果我得到一个XML文件结果作为数组，结果如下所示。如何将每个值存储到变量中

不仅仅是这种类型的数组，如果我们使用不同的XML文件或URL，其结果可能不是多维数组

如何在php变量中存储数组值

   <?php
function objectsIntoArray($arrObjData, $arrSkipIndices = array())
{
    $arrData = array();

    // if input is object, convert into array
    if (is_object($arrObjData)) {
        $arrObjData = get_object_vars($arrObjData);
    }

    if (is_array($arrObjData)) {
        foreach ($arrObjData as $index => $value) {
            if (is_object($value) || is_array($value)) {
                $value = objectsIntoArray($value, $arrSkipIndices); // recursive call
            }
            if (in_array($index, $arrSkipIndices)) {
                continue;
            }
            $arrData[$index] = $value;
        }
    }
    return $arrData;
}


$xmlUrl = "testxmel.xml"; // XML feed file/URL
$xmlStr = file_get_contents($xmlUrl);
$xmlObj = simplexml_load_string($xmlStr);
$arrXml = objectsIntoArray($xmlObj);

任何人都可以帮助我解决这个XML解析器结果问题。提前谢谢

// let's assume $myArray is your array

$guest = count( $myArray ); // no. of guests

foreach( $myArray as $guests ) {
   $name = $guests[ 'name' ];
   $age = $guests[ 'age' ];

   // work with this data here...
}

希望这有帮助

数组有什么问题？这是存储此类数据的最佳方式。PHP中不能有多个$name变量。之后您想对这些变量做什么？我的问题是如何将这些值存储在php变量中，如foreach（$arrXml as$row）{}数组有什么问题？这是存储此类数据的最佳方式。PHP中不能有多个$name变量。之后您想对这些变量做什么？我的问题是如何将这些值存储在php变量中，如以下foreach（$arrXml as$row）{}它将错误显示为“在E:\wamp\www\testxml.php的第31行为foreach（）提供的参数无效”我已将
$myArray
用作数组。用你的数组替换它。我也替换了它，但它不起作用。我认为数组计数是1。这就是它显示无效参数的原因。它将错误显示为“在E:\wamp\www\testxml.php的第31行为foreach（）提供的无效参数”我已将
