Question

我想在while循环中填充一个数组。

我想像这样显示这个数组：

category 1 => Company A => 'name', 'city', 'CEO',
              Company B => 'name', 'city', 'CEO'

category 2 =  Company A => 'name', 'city', 'CEO',
              Company B => 'name', 'city', 'CEO'

ect ........

这是我在while循环中的当前代码

$array_cat[] = array(
                 array(
                  'category' => $cat,
                      array(
                        'company' => array(

                            'name' => $name,
                            'city' => $city,
                            'CEO' => $ceo

                        )
                    )
                )
            );

我的代码我显示它

foreach ($array_cat as $item) {
    foreach ($array_cat['category'] as $company_display) {
        echo $company_display['company']['name'][];
    }
}

感谢您的帮助;）

Answer 1

试试这个：

$array1 = array('category1' => 
                array('Company A' => 
                        array('name', 'city', 'CEO')), 
                'category2' => 
                array('Company B' => 
                        array('name', 'city', 'CEO')));

foreach ($array1 as $key => $value) 
{
    foreach ($value as $key1 => $value1) 
    {
        echo "<pre>";
        print_r($value1);
        echo "</pre>";
    }
}

问题在于你的内在的foreach循环

Answer 2

内部foreach循环和回声线存在问题。

将 $ array_cat 替换为 $ item ，并在echo行中出现错误：无法使用 [] 进行阅读

通过以下方式，您可以实现目标。

如何在PHP中创建这个多维数组

如果我为此设计一个数组，我会做这样的事情：

$array = array(
    //Category 1, nameless i assume?
    array(
        //Companies
        "Company A" => array(
                            //Company properties
                            "name" => "My A company",
                            "city" => "Some city that starts with an A",
                            "CEO"  => "Some CEO that starts with an A"
                        ),
        "Company B" => array(
                            //Company properties
                            "name" => "My B company",
                            "city" => "Some city that starts with an B",
                            "CEO"  => "Some CEO that starts with an B"
                        ),
    ),

    //Category two, nameless i assume
    array(
        //Companies
        "Company C" => array(
                            //Company properties
                            "name" => "My C company",
                            "city" => "Some city that starts with an C",
                            "CEO"  => "Some CEO that starts with an C"
                        ),
        "Company D" => array(
                            //Company properties
                            "name" => "My D company",
                            "city" => "Some city that starts with an D",
                            "CEO"  => "Some CEO that starts with an D"
                        ),
    ),
);

然后，如果我想从中获取一些数据，我可以这样做：

$companyAcity = $array[0]['Company  A']['city'];

echo $companyAcity;

如果我想循环数组，我可以这样：

for($categoryID = 0; categoryID < count($array); $i++) {
   //Prints data for each category it loops through.
   echo $array[$categoryID];

   //Loops through the companies contained in the current category where it's looping through
   foreach($array[$categoryID] as $companyName => $companyData) {
      echo $companyName;
      echo $companyData['name'];
   }
}

我想在while循环中填充一个数组。

如果要在循环中向数组添加数据，可以执行以下操作：

for($categoryID = 0; categoryID < count($array); $i++) {
   $array[$categoryID][] = $categoryID +1;
}
