/***
This example defines a command line accepting one REQUIRED parameter, -string_value.
Note that you reserved parameters such as -help are processed first, so it's not necessary
to supply required values for displaying command-line help ; thus, the following will not
throw an exception but simply display command-line help :
$ php required.php -help
***/
require_once ( dirname ( __FILE__ ) . '/../examples.inc.php' ) ;
$definitions = <<<END
<command>
<usage>
Example script that demonstrates the usage of the "required" attribute.
Run it without any parameter ; An exception will be thrown because the -string_value parameter
is required :
\$ php required.php
Then with a value specified for the -string_value parameter :
\$ php default.php -string_value "hello world"
</usage>
<string name="string_value, sv" required="true">
Help for the string_value parameter.
</string>
</command>
END;
$cl = new CLParser ( $definitions ) ;
echo "Value of the -string_value parameter : {$cl -> string_value}\n" ;
