如何使数组中的所有键和值都拥有自己的数组

Question

假设我的数组如下所示：

Array
(
    [0] = Charcoal,Natural Gas,Combo
    [1] = Charcoal,Propane,Combo
    [2] = Charcoal,Propane,Natural Gas,Combo
    [3] = Natural Gas
)

我能做些什么让它看起来像这样：

Array
(
    [0] = Charcoal,Natural Gas,Combo
)
Array
(
    [0] = Charcoal,Propane,Combo
)
Array
(
    [0] = Charcoal,Propane,Natural Gas,Combo
)
Array
(
    [0] = Natural Gas
)

Answer 1

乍一看，我建议这样做：

$array = Array
(
    [0] = Charcoal,Natural Gas,Combo
    [1] = Charcoal,Propane,Combo
    [2] = Charcoal,Propane,Natural Gas,Combo
    [3] = Natural Gas
);
$array2 = array();
foreach ($array as $item) {
    $array2[][] = $item;
}

仔细想想，您并没有显示一个新的数组，而是显示了多个数组。这将意味着这样的实现：

foreach ($array as $item) {
    print_r($item);
}

Answer 2

您可以使用array_cchunk（）函数。

$array = array('Charcoal, Natural gas, Combo' ,'Charcoal,Propane,Combo', 'Charcoal,Propane,Natural Gas, Combo', 'Natural Gas' );
$arr = array_chunk($array,1);

参见演示

Answer 3

   ## hope this helps ##
  <?php
$array = Array('Charcoal, Natural 
Gas,Combo','Charcoal,Propane,Combo','Charcoal,Propane,Natural Gas,Combo', 'Natural 
Gas');
$d1 = array_slice($array, 0, 1);
$d2 = array_slice($array, 1, 1);
$d3= array_slice($array, 2, 1);
$d4 = array_slice($array, 3, 1);
echo "<pre>";
print_r($d1);
print_r($d2);
print_r($d3);
print_r($d4);
echo "</pre>";
