php中的嵌套键值查找
我正在尝试为学校的一个班级制作一个“股票”网站，这是我第一次涉足php。基本上，该脚本从GoogleDocs电子表格中提取一个CSV文件，并（尝试）将这些值放入数组中供以后使用。我想展示前五名股票的涨跌情况，但我遇到了一些问题。以下是脚本的主要部分：php中的嵌套键值查找,php,arrays,web,stocks,array-push,Php,Arrays,Web,Stocks,Array Push,我正在尝试为学校的一个班级制作一个“股票”网站，这是我第一次涉足php。基本上，该脚本从GoogleDocs电子表格中提取一个CSV文件，并（尝试）将这些值放入数组中供以后使用。我想展示前五名股票的涨跌情况，但我遇到了一些问题。以下是脚本的主要部分： <html> <head> <?php #Global Variables $rising = array(); $falling = array(); $stocks

我不太清楚你的代码，但我可以展示一个展示嵌套数组的示例：
$arr = array('1' => array('1', '2'), '2');
function showNested($array)
{
foreach($array as $key => $value)
{
if(is_array($value))
{
echo $value;
showNested($array);
}
else
{
echo $value;
}
}
}
您在代码中使用了
$stocks['$stockInfo[0]]{}[]$arr[]=$dataarray\u push
