php中读取数据库时有获得第一行第一列数据的函数吗？

比如我统计数据库的记录数
select count(*) from table1

这样的语句，必须要按照标准的query方法来获取记录集，然后再获取行，再获取列，是不是？

在asp.net中是直接有个函数可以获取查询语句产生记录集的第一行第一列数据的。

谢谢

回复讨论(解决方案)

PDO有专门的方法，自己查查手册
貌似是findColunm()。。。。。还是fetchColumn()。。。

pdo 中的 fetchColumn
mysql_ 系列函数好像要多写几步

也可以用mysql_num_rows() 函数，不过
select count(*) from table1
要改为
select * from table1

感谢楼上几位
