# Using short options
myphpscript -q -l en -o
# Using long options instead
myphpscript --quite --lang=en --option
# Mixing both
myphpscript -q --lang=en -o

You have to define which options you want to support. The second
argument of
getopt() requires a string containing
all supported chars. For the example above this would be at least:
<?php
$shortoptions = "qlo";
?>
|
The order of the characters is not important. Often you have
to define options with (optional) parameters. To express that
a option requires a parameter, you have to add a colon. If the
parameter is optional, add a double colon, ie:
<?php
$shortoptions = "ql:o::";
?>
|
this means the following script calls are permitted, ie.
myphpscript
myphpscript -q
myphpscript -q -l en
myphpscript -o text
myphpscript -o
|
whilst
is not permitted. The
-l
option
requires a parameter, if the option is used.
The long options work equally, but they have to be defined in
an array:
<?php
$longoptions = array("quite", "lang", "option");
?>
|
For defining optional parameters, use
'='
and
'=='
like the colon in short options.
<?php
$longoptions = array("quite", "lang=", "option==");
?>
