What are the steps to check if the necessary PHP extension for parsing YAML files is installed and available on a server?

To check if the necessary PHP extension for parsing YAML files is installed and available on a server, you can use the `extension_loaded` function in PHP. This function checks if a specific extension is loaded and available for use in the current PHP environment. By checking for the `yaml` extension, you can ensure that your server is capable of parsing YAML files. 

if (extension_loaded('yaml')) {
    echo "The YAML extension is installed and available on this server.";
} else {
    echo "The YAML extension is not installed on this server.";
}
