To elaborate on what 'ch1902' said, there certainly are instances where you may need to execute a script via CLI and the HTTP protocol. In such an instance, you can normalize how your script parses via CLI (using getopt()) as well as via HTTP (using $_GET) with the following simplified code:

<?php
// PHP 5.4+ only due to the new array brace style.
function request(array $options = []) {
    // Set the default values.
    $defaults = [
        'params' => '',
        'os' => '',
        'username' => posix_getpwuid(posix_geteuid())['name'],
        'env' => ''
    ];
    $options += $defaults;

    // Sufficient enough check for CLI.
    if ('cli' === PHP_SAPI) {
        return getopt('', ['params:', 'os::', 'username::', 'env::']) + $options;
    }
    return $_GET + $options;
}

print_r(request());
?>

The above code would yield the results below when access via CLI and HTTP.

/**
 * params = foo/bar
 * username = housni.yakoob
 */
// CLI
$ php script.php --params=foo/bar --username=housni.yakoob
Array
(
    [params] => foo/bar
    [username] => housni.yakoob
    [os] => 
    [env] => 
)

// HTTP
script.php?params=foo/bar&username=housni.yakoob
Array
(
    [params] => foo/bar
    [username] => housni.yakoob
    [os] => 
    [env] => 
)

/**
 * params = foo/bar
 * username = Not provided, therefore, the default value will be used.
 */
// CLI
$ whoami && php script.php --params=foo/bar
housni // <-- Current users usersname (output of `whoami`).
Array
(
    [params] => foo/bar
    [os] => 
    [username] => housni
    [env] => 
)

// HTTP
script.php?params=foo/bar
Array
(
    [params] => foo/bar
    [os] => 
    // The username of my Apache user, the result of posix_getpwuid(posix_geteuid())['name']
    [username] => www-data
    [env] => 
)

As you can see, the output is consistent when the script is executed via the CLI or the web.
