What are the potential pitfalls of working with bzip2 files in PHP and how can they be avoided?

Potential pitfalls of working with bzip2 files in PHP include not properly handling errors, not checking if the bzip2 extension is installed, and not properly closing the file handles after use. To avoid these pitfalls, always check for errors when working with bzip2 functions, verify that the bzip2 extension is installed on the server, and make sure to close file handles properly. 

// Check if bzip2 extension is installed
if (!extension_loaded('bz2')) {
    die('bzip2 extension is not installed. Please install it before using bzip2 functions.');
}

// Open bzip2 file for reading
$filename = 'example.bz2';
$handle = bzopen($filename, 'r');
if (!$handle) {
    die('Failed to open bzip2 file for reading.');
}

// Read data from bzip2 file
$data = '';
while (!feof($handle)) {
    $data .= bzread($handle, 4096);
}

// Close bzip2 file handle
bzclose($handle);
