What potential issues can arise when using gzopen in PHP on different server environments?

When using gzopen in PHP on different server environments, potential issues can arise due to differences in server configurations or availability of the zlib extension. To ensure compatibility, you can check if the zlib extension is loaded before using gzopen. This can be done using the function extension_loaded('zlib'). 

if (extension_loaded('zlib')) {
    $file = gzopen('example.txt.gz', 'r');
    // Perform operations with the gzipped file
    gzclose($file);
} else {
    echo 'Zlib extension is not available.';
}
