Appending a file in PHP

In PHP, appending a file means adding new content to the end of an existing file without overwriting the existing data. This can be done using the “fopen” function with the “a” parameter, which opens the file for appending.

Once the file is opened for appending, you can use the “fwrite” function to write new content to the file. The new content will be added to the end of the existing data in the file.

It’s important to note that you need to have write permission on the file in order to append to it. Also, if the file does not exist, it will be created when you open it for appending.
