What are the potential pitfalls of using fsockopen() to read and save .txt.gz files in PHP?

Potential pitfalls of using fsockopen() to read and save .txt.gz files in PHP include potential issues with handling compressed data and managing file permissions. To solve this, it is recommended to use PHP's built-in functions like gzopen() and gzread() to handle compressed files more efficiently and reliably. 

// Open a .txt.gz file using gzopen() instead of fsockopen()
$filename = 'example.txt.gz';
$handle = gzopen($filename, 'r');

if ($handle) {
    // Read the contents of the file
    $contents = gzread($handle, filesize($filename));

    // Save the contents to a new file
    file_put_contents('uncompressed_example.txt', $contents);

    // Close the file handle
    gzclose($handle);
} else {
    echo "Failed to open file.";
}
