/* _getopt(): Ver. 1.3 2009/05/30
My page: http://www.ntu.beautifulworldco.com/weblog/?p=526
Usage: _getopt ( [$flag,] $short_option [, $long_option] );
Note that another function split_para() is required, which can be found in the same
page.
_getopt() fully simulates getopt() which is described at
http://us.php.net/manual/en/function.getopt.php , including long options for PHP
version under 5.3.0. (Prior to 5.3.0, long options was only available on few systems)
Besides legacy usage of getopt(), I also added a new option to manipulate your own
argument lists instead of those from command lines. This new option can be a string
or an array such as
$flag = "-f value_f -ab --required 9 --optional=PK --option -v test -k";
or
$flag = array ( "-f", "value_f", "-ab", "--required", "9", "--optional=PK", "--option" );
So there are four ways to work with _getopt(),
1. _getopt ( $short_option );
it's a legacy usage, same as getopt ( $short_option ).
2. _getopt ( $short_option, $long_option );
it's a legacy usage, same as getopt ( $short_option, $long_option ).
3. _getopt ( $flag, $short_option );
use your own argument lists instead of command line arguments.
4. _getopt ( $flag, $short_option, $long_option );
use your own argument lists instead of command line arguments.
