What are the limitations of accessing files outside the public directory in a Zend environment?

Accessing files outside the public directory in a Zend environment can pose security risks as it exposes sensitive information to potential attackers. To mitigate this risk, it is recommended to restrict file access to only the necessary directories within the public directory. 

// Restrict file access to only the necessary directories within the public directory
$filePath = '/path/to/public/directory/file.txt';
if (strpos(realpath($filePath), realpath('/path/to/public/directory')) !== 0) {
    throw new Exception('Access to this file is restricted.');
}

// Access the file within the public directory
$fileContent = file_get_contents($filePath);
echo $fileContent;
