Explanation

The above code snippets demonstrate how to create, delete, and copy a file from a PHP Script. The fopen function is the first step for creating a file. The w parameter indicates the file should be written to. If the fwrite function is used, the given string is written into the file that has just been created. To delete the file, we employ the file_exists function to detect the existence of the file and use unlink to delete the file. To copy a file, we use the copy function and specify both the source and destination of the file.
