Question

我想将字符串转换为多维数组，以便我可以在无序列表中显示它

$ notes变量的内容：

Conditions:
  Adult fares apply from 13 years old and above. Child fares apply from 4 to 
  12 years old
  Infants not included

What to bring:
  Sunscreen, water bottle, hat, sunglasses, camera, small 7kg overnight bag 
  if using the hop on hop off option

What to wear:
  Warm clothes, windbreaker, comfortable walking shoes

Insurance: 
  We highly recommend all passengers have travel insurance coverage

Optional extras paid on arrival:
  Helicopter joy flight over the 12 Apostles AUD145

Not included:
  Dinner (at own expen

想要像这样的输出

  [
     'conditions => ['some','some'],
     'what to bring' => ['content','content']
     .......
  ]

到目前为止我尝试使用爆炸功能

   explode(',',$notes)

但这是我不想要的输出

 array:8 [
    0 => """
       Conditions:\n
       Adults fares ....
       \n
      What to bring
      .....
    1 => "water bottle"
    2 => "hat"
    ......
 ]

因此预期输出为无序列表

     conditions
          1. ....
          2.....
     what to bring
           1....
           2....
     Inurance
           1..
           2...

请注意，键（条件，带来的内容......）是动态名称，因此它可能会不时更改，但格式相同

有什么建议吗？

您可以按EOL分解字符串，循环遍历数组并检查字符串是否以:结尾，如果是，则将其用作密钥。

$notes = ''; //Your string here

//Init variables
$final = array();
$tempKey = "";

//Convert the string into an array
$arr = array_filter(explode(PHP_EOL, $notes), 'trim');

//Loop thru the array
foreach($arr as $val) {
    if ( substr(trim($val), -1) === ':' ) $tempKey = rtrim(trim($val),":");
    else $final[ $tempKey ][] = trim($val);
}

echo "<pre>";
print_r( $final );
echo "</pre>";

这将导致：

Array
(
    [Conditions] => Array
        (
            [0] => Adult fares apply from 13 years old and above. Child fares apply from 4 to
            [1] => 12 years old
            [2] => Infants not included
        )

    [What to bring] => Array
        (
            [0] => Sunscreen, water bottle, hat, sunglasses, camera, small 7kg overnight bag
            [1] => if using the hop on hop off option
        )

    [What to wear] => Array
        (
            [0] => Warm clothes, windbreaker, comfortable walking shoes
        )

    [Insurance] => Array
        (
            [0] => We highly recommend all passengers have travel insurance coverage
        )

    [Optional extras paid on arrival] => Array
        (
            [0] => Helicopter joy flight over the 12 Apostles AUD145
        )

    [Not included] => Array
        (
            [0] => Dinner (at own expen
        )

)

将String转换为数组或多维数组，并将特定字符串作为键
