여러 URL/경로를 다차원 배열로 병합하는 방법은 무엇입니까?

Question

나는 다음과 같은 배열을 가지고 :

$path = array (
[0] => site\projects\terrace_and_balcony\mexico.jpg 
[1] => site\projects\terrace_and_balcony\new_york.jpg 
[2] => site\projects\terrace_and_balcony\berlin.jpg 
[3] => site\projects\terrace_and_balcony\Kentucky.jpg 
[4] => site\projects\terrace_and_balcony\Utah.jpg 
[5] => site\projects\terrace_and_balcony\Hawaii.jpg 
[6] => site\projects\private_gardens\mexico.jpg 
[7] => site\projects\private_gardens\new_york.jpg 
[8] => site\projects\private_gardens\berlin.jpg 
[9] => site\projects\private_gardens\Kentucky.jpg 
[10] => site\projects\private_gardens\Utah.jpg 
[11] => site\projects\private_gardens\Hawaii.jpg 
) 

어떻게 그로 변환 :

$path11 = array 
(
    "site"=>array 
    (
     "projects"=>array 
     (
      "terrace_and_balcony"=>array 
      (
       "mexico.jpg", 
       "new_york.jpg", 
       "berlin.jpg", 
       "Kentucky.jpg", 
       "Utah.jpg", 
       "Hawaii.jpg" 
      ), 
      "private_gardens"=>array 
      (
       "mexico.jpg", 
       "new_york.jpg", 
       "berlin.jpg", 
       "Kentucky.jpg", 
       "Utah.jpg", 
       "Hawaii.jpg" 
      ) 
     ) 
    ) 
);

$pathStrings = [ 
    'site\\projects\\terrace_and_balcony\\mexico.jpg', 
    'site\\projects\\terrace_and_balcony\\new_york.jpg', 
    'site\\projects\\terrace_and_balcony\\berlin.jpg', 
    'site\\projects\\terrace_and_balcony\\Kentucky.jpg', 
    'site\\projects\\terrace_and_balcony\\Utah.jpg', 
    'site\\projects\\terrace_and_balcony\\Hawaii.jpg', 
    'site\\projects\\private_gardens\\mexico.jpg', 
    'site\\projects\\private_gardens\\new_york.jpg', 
    'site\\projects\\private_gardens\\berlin.jpg', 
    'site\\projects\\private_gardens\\Kentucky.jpg', 
    'site\\projects\\private_gardens\\Utah.jpg', 
    'site\\projects\\private_gardens\\Hawaii.jpg' 
]; 

$paths = []; 
foreach ($pathStrings as $pathString) { 
    // Split by the delimiter. 
    $pathParts = explode('\\', $pathString); 

    // Build a nested assoc array representing the path. 
    // Each key and value comes from the delimited parts of the string. 
    // eg: site\projects\terrace_and_balcony\mexico.jpg 
    // becomes: [ 
    //  'site' => [ 
    //    'projects' => [ 
    //      'terrace_and_balcony' => [ 
    //        'mexico.jpg' 
    //      ] 
    //    ] 
    //  ] 
    // ] 
    $path = [array_pop($pathParts)]; 
    foreach (array_reverse($pathParts) as $pathPart) { 
     $path = [$pathPart => $path]; 
    } 

    // Add it to a temp list. 
    $paths[] = $path; 
} 

// Now, merge all the paths together recursively at once. 
$tree = call_user_func_array('array_merge_recursive', $paths); 

// Done. 
print_r($tree);

당신이 필요로() 함수와 foreach는 루프를 폭발입니다.
