PHP function getopt Detailed

Short Parameters
It returns an array containing command-line arguments. For example, to get the value of-a-b and-C, you can do this:
$arguments = getopt ("A:B:C:");
You can run the script in the following way (there are no spaces are not related, note the first example and the second example):

PHP test.php-a app-b bar-c carorphp Test.php-aapp-bbar-ccar

Print_r ($arguments) will return:

Array (    [a] + = App    [b] = bar    [c] = car)

Attention:
1. The colon is required
2. If no value is specified, it will not appear in the array
Or just the example:

PHP test.php-a App

Print_r ($arguments):

Array (    [a] + = app)

About Long parameters
Earlier than PHP 5.3, if you use a long parameter (--name=value or--name value), you will probably get the following error message:
PHP warning:getopt (): No support for long options in the This build in ...
Therefore, it is best to use short parameters if the PHP version is earlier than 5.3.
