what is signature of behaviors in yii? should this be a function or a class method? Can any provide sample code?
There is no signature for behaviors, as behaviors are intented to add some function to class. Only requirement is to extend from CBehavior
. Like in wiki or docs:
class SomeClass extends CBehavior
{
public function add($x, $y) { return $x + $y; }
}
class Test extends CComponent
{
public $blah;
}
$test = new Test();
// Attach behavior
$test->attachbehavior('blah', new SomeClass);
// Now you can call `add` on class Test
$test->add(2, 5);
However since PHP 5.4 you can use Traits which are native php implementation and have a lot more features, example above with traits:
// NOTE: No need to extend from any base class
trait SomeClass
{
public function add($x, $y) { return $x + $y; }
}
class Test extends CComponent
{
// Will additionally use methods and properties from SomeClass
use SomeClass;
public $blah;
}
$test = new Test();
// You can call `add` on class Test because of `use SomeClass;`
$test->add(2, 5);
There are a lot more features with traits
