Are there any best practices for storing and managing files in higher-level directories in PHP?

When storing and managing files in higher-level directories in PHP, it is important to ensure proper permissions are set for the directories to prevent unauthorized access. It is also recommended to use absolute file paths when accessing files to avoid any potential issues with relative paths. Additionally, organizing files into separate directories based on their purpose or type can help with better file management. 

// Example of storing and managing files in higher-level directories in PHP

// Define the base directory where files will be stored
$baseDir = '/path/to/base/directory/';

// Create a new directory for storing uploaded files
$uploadDir = $baseDir . 'uploads/';
if (!file_exists($uploadDir)) {
    mkdir($uploadDir, 0777, true);
}

// Save a file to the uploads directory
$uploadedFile = $_FILES['file']['tmp_name'];
$destinationFile = $uploadDir . $_FILES['file']['name'];
move_uploaded_file($uploadedFile, $destinationFile);

// Access a file from the uploads directory
$fileToAccess = $uploadDir . 'example.txt';
if (file_exists($fileToAccess)) {
    $fileContents = file_get_contents($fileToAccess);
    echo $fileContents;
} else {
    echo 'File not found.';
}
