У меня такой массив:
$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 ) Как преобразовать его в это:
$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);,$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);

Все, что вам нужно, это функция explode () и петли foreach.
