How can I replace the specified character nihao in c: \ a.txt with haha with a new file c: \ B .txt with a JS command?

Note: c: \ a.txt contains a lot of messy code, but only one nihao character

------ Solution --------------------

PHP code

$ Contents = file_get_contents ("c: \ a.txt"); if (! $ Contents) exit ("check whether the file path is correct"); $ new_contents = str_replace ("nihao", "haha", $ contents); file_put_contents ("c: \ B .txt ", $ new_contents );
