/**
|
||
|
|
* ArgvInput represents an input coming from the CLI arguments.
|
||
|
|
*
|
||
|
|
* Usage:
|
||
|
|
*
|
||
|
|
* $input = new ArgvInput();
|
||
|
|
*
|
||
|
|
* By default, the `$_SERVER['argv']` array is used for the input values.
|
||
|
|
*
|
||
|
|
* This can be overridden by explicitly passing the input values in the constructor:
|
||
|
|
*
|
||
|
|
* $input = new ArgvInput($_SERVER['argv']);
|
||
|
|
*
|
||
|
|
* If you pass it yourself, don't forget that the first element of the array
|
||
|
|
* is the name of the running application.
|
||
|
|
*
|
||
|
|
* When passing an argument to the constructor, be sure that it respects
|
||
|
|
* the same rules as the argv one. It's almost always better to use the
|
||
|
|
* `StringInput` when you want to provide your own input.
