Here it is my code to upload an audio file. I tried lot of questions and answers in stackoverflow. But still i am not getting any improvement on this. I have to upload an audio file with a php link. If i do that, i am getting response like "already exists" always. I tried to change the filename and upload it. still getting same response. Actually i have to receive a response from the server as link of a file i uploaded. I am not having any knowledge about php. Anyone help me with this. Any help would be appreciated to clear my issue.
