PHP中可以这样写if语句吗？还是我想多了

public function getAreaList($pid = -1) {<br />
		$map = array();<br />
		$pid != -1 && $map['pid'] = $pid;<br />
		return $this->where($map)->order('`area_id` ASC')->findAll();<br />
	}
Copy after login


$pid != -1 && $map['pid'] = $pid;
return $this->where($map)->order('`area_id` ASC')->findAll();
这两句没条件关系吧？上面的一句为什么要用&&连接呢？与直接写
$pid != -1;
$map['pid'] = $pid;
的区别是什么呢？
