我有一个包含几个名为.txt的文件的文件夹:
A500_1.txt
A500_2.txt
A700_1.txt
A700_2.txt
A900_1.txt
...
在每个.txt文件中都有:
PRXC1_|TB|CCAAO9-RC|9353970324463|24.99
PRXC1_|TB|CFEXK4-RC|9353970294766|84.99
PRXC1_|TB|CFEXK4-RC|9353970294773|84.99
...
我希望你:
如果文件名以A500_开头,则将“ TB”替换为“ MD”
如果文件名以A700开头,请用“ JB”替换“ TB”
如果文件名发送者代码在此处用A900_替换,则将“ TB”替换为“ LD”
我编写了此函数,但它只是为我创建了一个空的A500_2.TXT文件并显示:
警告:file_get_contents(A500_2.TXT):打开流失败:
我的错误在哪里?
