Php deletes a specified file in a folder. I want code, thank you, and do not want to copy, such as 111.txt and unlink ('./upload/111.txt') under the uploadfile folder. // do not copy the correct path? Can't I copy it ?, Do {echo & quot; [delete a specified file in the folder using php. Code. thank you. do not copy it.
For example, 111.txt under the uploadfile folder

------ Solution --------------------
Unlink ('./upload/111.txt'); // note that the path is correct.

What do you mean by not copying? Can't I copy it?
------ Solution --------------------
Do {
Echo "[title]: {$ sbxw ['falsename']} delete the book {$ sbxw ['id']}
";
} While ($ sbxw = mysql_fetch_array ($ SQL ));
