YX1209=YX1209,545.00,547.00,552.00,551.00,6893,256324,552.00,6603,117688,553.00,546.00,549.00,7.00,1308386,452116,718696576.00,583.00,506.00

SW1209=SW1209,61.00,61.80,61.30,61.30,5037,1113470,61.40,6973,169972,62.00,60.70,61.30,0.30,1478284,455310,90644015.20,65.20,56.70

這個意思,preg_replace找數字之後跟英文字母的地方，換上一個\n。
