Are there any specific PHP functions or libraries that are recommended for file system operations?

When working with file system operations in PHP, it is recommended to use the built-in functions provided by the language to ensure efficiency and security. Some commonly used functions for file system operations in PHP include file_exists(), fopen(), fwrite(), fclose(), and unlink(). Additionally, the SplFileObject class can be used for more advanced file handling operations. 

// Check if a file exists
$file_path = 'example.txt';
if (file_exists($file_path)) {
    echo 'File exists!';
} else {
    echo 'File does not exist.';
}

// Read from a file
$file_handle = fopen($file_path, 'r');
while (!feof($file_handle)) {
    $line = fgets($file_handle);
    echo $line;
}
fclose($file_handle);

// Write to a file
$file_handle = fopen($file_path, 'w');
fwrite($file_handle, 'Hello, World!');
fclose($file_handle);

// Delete a file
unlink($file_path);
