PHP试图包含glob（）目录的数组，但未找到最后一个

Question

Hello I have the following method:

private static function loadIncludes()
{
    // prepare array of files from folders
    $files = array(
        glob(self::libPath()."/*.php"),
        glob(self::controllersPath()."/*.php"),
        glob(self::extensionsPath()."/*.php"),
    );

    // include files
    foreach ($files as $set)
    {
        if (is_array($set)) foreach ($set as $file)
        {
            require_once($file);
        }
    }
}

If I print_r the $files array it contains all the files but for some reason its not doing a require_once() on the last array item (/home/ * /app/extensions/Controller.php) see output:

Array
(
    [0] => Array
        (
            [0] => /home/***/app/lib/CApp.php
            [1] => /home/***/app/lib/CController.php
            [2] => /home/***/app/lib/CDb.php
            [3] => /home/***/app/lib/CView.php
        )

    [1] => Array
(
            [0] => /home/***/app/controllers/SiteController.php
        )

    [2] => Array
(
            [0] => /home/***/app/extensions/Controller.php
        )

)

As the print_r shows even when there is only a single result it still an array,

I believe the if (is_array($set)) can be left out.

As for why only the last one doesn't work i cannot say,

try debugging better by echoing every step of all for each loops
