Hi, I know && is Logical Operators in programming language.
But when I go through the The [color="#4169E1"]Definite Guide to Yii [/color], here is a example at
http://www.yiiframework.com/doc/guide/form.table documents.
In the actionBatchUpdate() method, there is a statement says: [color="#4169E1"]$valid=$valid && $item->validate();
[/color]
Could anyone tell me what does && means in this case?

I the first operand evaluates to false, no need to evaluate the second operand.
