php-将二维数组转换为单维数组

Question

I am reading my css folder and received the below array.

Array
(
    [FormValidation] => Array
        (
            [0] => formValidation.css
        )

    [0] => bootstrap-theme.css
    [1] => bootstrap-theme.min.css
    [2] => bootstrap.css
    [3] => bootstrap.min.css
    [4] => component.css
    [5] => custom.css
    [6] => custom_11_1_backup.css
    [7] => datepicker.css
    [8] => dropkick.css
    [9] => easy-responsive-tabs.css
    [10] => jquery.bootstrap-touchspin.css
    [11] => jquery.fileupload.css
    [12] => jquery.mCustomScrollbar.css
    [13] => jquery.noty.css
    [14] => noty_theme_default.css
    [15] => owl.carousel.css
    [16] => owl.theme.css
    [17] => owl.theme.default.min.css
    [18] => print_invoice.css
    [slider] => Array
        (
            [0] => AjaxLoader.gif
            [1] => owl.theme.css
        )

    [19] => validationEngine.jquery.css
)

Now I want these like in below format.

Array
(
    [0] => Array
        (
            [path] => css/FormValidation/formValidation.css
            [name] => formValidation.css
        )

    [1] => Array
        (
            [path] => css/bootstrap-theme.css
            [name] => bootstrap-theme.css
        )
)

I dont know how to handle the recursive array for the folders.

Answer 1

Ok, here's a solution with a recursive call of a function.

Code

    <?php
        $data = array(
            'FormValidation' => array (
                   0 => 'formValidation.css'
            ),
            0 => 'bootstrap-theme.css',
            1 => 'bootstrap-theme.min.css',
            2 => 'bootstrap.css',
            3 => 'bootstrap.min.css',
            4 => 'component.css',
            5 => 'custom.css',
            'slider' => array (
                0 => 'AjaxLoader.gif',
                1 => 'owl.theme.css',
            ),
            19 => 'validationEngine.jquery.css',
        );

        $initpath = 'css';
        echo '<b>INPUT</b><pre>'; var_dump($data); echo '</pre>';    // for testing purpose only
        $result = extractStyleSheets($data, $initpath);
        echo '<b>RESULT</b><pre>'; var_dump($result); echo '</pre>'; // for testing purpose only

        function extractStyleSheets($input,$path='') {
            $result = array();
            $success = true;
            foreach($input as $key => $item) {
                if (is_array($item)) { // It's an array, so we have a sub-level
                    // Recursive call of function and merging the arrays
                    $result = array_merge(
                        $result, 
                        extractStyleSheets($item,$path . (empty($path) ? '' : '/') . $key)
                    );
                } else {
                    // For style sheets only do
                    if (preg_match('/(.*?\.css)/i', $item, $regs)) {
                        // Push a sub-array to the result array
                        $result[] = array(
                            'path' => $path . '/' . $item,
                            'name' => $item
                            );
                    }
                }
            }
            return $result;
        }
    ?>

Result

array(9) {
    [0]=> array(2) { 
        ["path"]=> string(37) "css/FormValidation/formValidation.css"
        ["name"]=> string(18) "formValidation.css"
