php - php 构建/填充数组数组

Question

我已经看过很多关于如何从二维数组中获取数据的教程，但我需要构建一个与此类似的教程，但我没有找到任何可以遵循的逻辑：

$array = array("socks" => array("blue", "red", "green"),
               "shirts"  => array("small", "medium", "large"));

我似乎无法弄清楚甚至启动代码的逻辑....

for each clothingType // I did this
  get options // I did this
    for each option //I did this
       add to the clothingOption Array //... help!

我只停留在clothingOption 2D Array的构建上

会不会有点像

foreach clothingType as $kClothes =>VClothes
    get Options
      for each Options as $kOptions =>$VOption
      $array[$VClothes][]= $VOption

谢谢，我希望这不是太模糊......

Answer 1

也许（抱歉错误 - 手动）：

//$array = array("socks" => array("blue", "red", "green"),
//           "shirts"  => array("small", "medium", "large"));

$types = array('socks', 'shirts');
$socks = array("blue", "red", "green");
$shirts = array("small", "medium", "large");
$array = array();
foreach ($types as $type) {
    foreach($$type as $cloth) {
        $array[$type][] = $cloth;
    }
}
print_r($array);

Answer 2

下面的呢？

<?php
function getMe($type) {
  //do some processing and construct array
 return array('a','b','c');
}

$myTypes = array('type1','type2','type3');
$answer = array();
foreach($myTypes as $val) {
  $answer[$val] = getMe($val);
}

print_r($answer);
?>

输出：

Array ( [type1] => Array ( [0] => a [1] => b [2] => c ) [type2] => Array ( [0] => a [1] => b [2] => c ) [type3] => Array ( [0] => a [1] => b [2] => c ) )
