What conventions should be followed when using getopt() in PHP for command line scripts?

When using getopt() in PHP for command line scripts, it is important to follow certain conventions to ensure clarity and consistency in your code. One convention is to define the options and their corresponding values in a clear and organized manner. Another convention is to provide helpful comments to explain the purpose of each option and its expected value. Additionally, it is recommended to handle errors gracefully and provide informative messages to the user if an invalid option is passed. 

$options = getopt("a:b:c:");
if (empty($options) || count($options) < 3) {
    echo "Usage: script.php -a <valueA> -b <valueB> -c <valueC>\n";
    exit(1);
}

// Process options
$valueA = $options['a'];
$valueB = $options['b'];
$valueC = $options['c'];

// Perform actions based on the options
// ...
