declareVars() : voidDeclare template vars to set default values and avoid notices when using strictVars
Primarily for use when using {@link Zend_View_Abstract::strictVars() Zend_View strictVars()},
this helper can be used to declare template variables that may or may
not already be set in the view object, as well as to set default values.
Arrays passed as arguments to the method will be used to set default
values; otherwise, if the variable does not exist, it is set to an empty
string.
Usage:
$this->declareVars(
'varName1',
'varName2',
array('varName3' => 'defaultValue',
'varName4' => array()
)
);
