求正则表达式

[mayanly]

本人对正则不是很了解，求一个表达式把以下字符按照9个一组分别显示
,K0033206,K0033797,K0040687,K0040690,K0041011,Z0050997,P0001113,P0001187,P0003789*,P0003874*,P0009381,P0010403,P0010635,S0000022,S0000023,S0000036,X0000236,X0000245,X0000326
显示如下
,K0033206,K0033797,K0040687,K0040690,K0041011,Z0050997,P0001113,P0001187,P0003789*
,P0003874*,P0009381,P0010403,P0010635,S0000022,S0000023,S0000036,X0000236,X0000245
急需！

以逗号分割字符串，然后用数组下标取9个不行吗

[mayanly]

具体怎么做？

大概，2千多条数据，每9个画成一行。数组下标怎么标
