Laravel 5.2 cache notes

cache.md

Cache file name

• Just an md5 of the cache key
• Therefore not possible to identify key name from file name - md5 is one way

Cache directory name

• Level 1 - First 2 characters of filename
• Level 2 - Next 2 characters of filename

$storage = \Cache::getStore(); // will return instance of FileStore
$filesystem = $storage->getFilesystem(); // will return instance of Filesystem
$dir = (\Cache::getDirectory());
$keys = [];
foreach ($filesystem->allFiles($dir) as $file1) {
    if (is_dir($file1->getPath())) {
        foreach ($filesystem->allFiles($file1->getPath()) as $file2) {
            $keys = array_merge($keys, [$file2->getRealpath() => unserialize(substr(\File::get($file2->getRealpath()), 10))]);
        }
    }
