What are the limitations of PHP in accessing the client's filesystem?

PHP has limitations in accessing the client's filesystem due to security concerns. It is not recommended to directly access the client's filesystem as it can pose a risk of exposing sensitive information or allowing unauthorized access. To work around this limitation, it is best to use server-side file handling functions provided by PHP to interact with files on the server rather than the client's filesystem. 

// Example of using PHP file handling functions to read a file from the server
$file = 'example.txt';
if (file_exists($file)) {
    $content = file_get_contents($file);
    echo $content;
} else {
    echo "File not found.";
}
