discuz x2.5中关于discuz_database类的问题

<br />
	public static function delete($table, $condition, $limit = 0, $unbuffered = true) {<br />
		if (empty($condition)) {<br />
			return false;<br />
		} elseif (is_array($condition)) {<br />
			if (count($condition) == 2 && isset($condition['where']) && isset($condition['arg'])) {<br />
				$where = self::format($condition['where'], $condition['arg']);<br />
			} else {<br />
				$where = self::implode_field_value($condition, ' AND ');<br />
			}<br />
		} else {<br />
			$where = $condition;<br />
		}<br />
		$limit = dintval($limit);<br />
		$sql = "DELETE FROM " . self::table($table) . " WHERE $where " . ($limit ? "LIMIT $limit" : '');<br />
		return self::query($sql, ($unbuffered ? 'UNBUFFERED' : ''));<br />
	}<br />
该方法中的$where = self::format($condition['where'], $condition['arg']);21.$condition['arg']是什么意思指什么？<br />

数组里的一个键值

他应该 是这样的  delete删除方法  里面 肯定要条件 这个方法内部 最这个条件格式花下  在拼接成最后的sql  至于$condition['arg'] 你直接打印下 不就知道了 .....
