将txt文件的内容分解为数组

我在分解 .txt 文件的内容时遇到问题（结构如下）：

    01Name 1 
    02whatever contents
    03whatever contents
    -------------------
    01Name 2
    02whatever contents
    03whatever contents

正如你所看到的，“分隔符”是“--------------------”。现在的问题是：如何将此文件分解为数组，以便我可以搜索特定名称并显示该块的内容？我尝试过像这样爆炸：

  header("Content-type:text/plain");
  $file = fopen("cc/cc.txt", "r");


  while (!feof($file)) {
    $lot = fgets($file);
    $chunk = explode("-------------------",$lot);

    print_r($chunk);

  }

  fclose($file);             

并得到了这样的结果：

    Array
    (
        [0] => 01Name 1 

    )
    Array
    (
        [0] => 02whatever contents

    )
    Array
    (
        [0] => 03whatever contents

    )
    Array
    (
        [0] => -------------------

    )
    Array
    (
        [0] => 01Name 2

    )
    Array
    (
        [0] => 02whatever contents

    )
    Array
    (
        [0] => 03whatever contents
    )        

当我想得到这个结果时：

    Array
    (
        [0] => 01Name 1
        [1] => 02whatever contents
        [2] => 03whatever contents

    )
    Array
    (
        [0] => 01Name 2
        [1] => 02whatever contents
        [2] => 03whatever contents
    )

我已经搜索过PHP；将 fgets() 输出分配给数组 https://stackoverflow.com/questions/8479672/php-assigning-fgets-output-to-an-array and 读取txt文件的每一行到新的数组元素 https://stackoverflow.com/questions/6159683/read-each-line-of-txt-file-to-new-array-element，没有运气。

有什么想法吗？

您可以使用以下内容

$result = array();
$file = explode("-------------------", file_get_contents("cc/cc.txt"));
foreach ( $file as $content ) {
    $result[] = array_filter(array_map("trim", explode("\n", $content)));
}
var_dump($result);

Output

array
  0 => 
    array
      0 => string '01Name 1' (length=8)
      1 => string '02whatever contents' (length=19)
      2 => string '03whatever contents' (length=19)
  1 => 
    array
      1 => string '01Name 2' (length=8)
      2 => string '02whatever contents' (length=19)
      3 => string '03whatever contents' (length=19)

你可以更进一步

$result = array();
$file = explode("-------------------", file_get_contents("cc/cc.txt"));
foreach ( $file as $content ) 
{
    foreach(array_filter(array_map("trim",explode("\n", $content))) as $line)
    {
        list($key,$value) = explode(" ", $line);
        $result[$key] = $value ;
    }
}
var_dump($result);

Output

array
  '01Name' => string '2' (length=1)
  '02whatever' => string 'contents' (length=8)
  '03whatever' => string 'contents' (length=8)
