php - parse - ¿Cómo combinar múltiples url/path en una matriz multidimensional?

php string tokenizer

Question

Tengo una matriz como esta:

$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
)

Cómo convertirlo a eso:

$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"
            )
        )
    )
);

Answer 1

Todo lo que necesita es la función explode () y los bucles foreach.

Answer 2

$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);
