First, consider the verbose/quiet example. If we want //Horde_Argv//
to set verbose to TRUE unless "-q" is seen, then we can do this:
<code type="php">
-$parser->addOption('-v', array('action' => 'store_true', 'dest' =>
'verbose', $default => true));
+$parser->addOption('-v', array('action' => 'store_true', 'dest' =>
'verbose', 'default' => true));
$parser->addOption('-q', array('action' => 'store_false', 'dest' =>
'verbose'));
</code>
Oddly enough, this is exactly equivalent:
<code type="php">
$parser->addOption('-v', array('action' => 'store_true', 'dest' =>
'verbose'));
-$parser->addOption('-q', array('action' => 'store_false', 'dest' =>
'verbose', $default => true));
+$parser->addOption('-q', array('action' => 'store_false', 'dest' =>
'verbose', 'default' => true));
</code>
Those are equivalent because you're supplying a default value for
the option's destination, and these two options happen to have the
same destination (the verbose variable).
Consider this:
<code type="php">
-$parser->addOption('-v', array('action' => 'store_true', 'dest' =>
'verbose', $default => false));
-$parser->addOption('-q', array('action' => 'store_false', 'dest' =>
'verbose', $default => true));
+$parser->addOption('-v', array('action' => 'store_true', 'dest' =>
'verbose', 'default' => false));
+$parser->addOption('-q', array('action' => 'store_false', 'dest' =>
'verbose', 'default' => true));
</code>
Again, the default value for verbose will be TRUE: the last default
value supplied for any particular destination attribute is the one
that counts.
