Answer 1

尝试XDebug ，它将替换var_dump以显示出来，包括语法着色和缩进。

Answer 2

For beautiful lightweight debug, Kint does the job. Xdebug is great, but seems a little overkill to install, if only for pretty print or var_dump replacement.

Answer 3

It seems you want to output a list of file paths from some recursive directory structure. This function should help:

function createPaths(array $files, $prefix = '') {
    $paths = array();

    foreach ($files as $folder => $file) {
        if (is_array($file)) {
            $subPaths = createPaths($file, $prefix . $folder . '/');
            $paths = array_merge($paths, $subPaths);
        } else {
            $paths[] = $prefix . $file;
        }
    }

    return $paths;
}

$files = array(
    'Corners' => array(
        'original' => array(
            '1.jpg',
            '2.gif',
        ),
    ),
    'foo.jpg'
);

var_dump(createPaths($files));

Try print_r($files); . Maybe that will expand all arrays.
