What is use of copy () function?

Definition and Usage The copy() function copies a file. Note: If the to_file file already exists, it will be overwritten.

How do you copy & delete a files in PHP by using copy and unlink?

PHP File handling functions :copy() – used to copy a file. rename() – used to rename a file. unlink() – used to delete a file.

You can use the copy function as:

if ( copy($srcFilename,$destPath) ) {
  // file copied.
} else {
  // error occurred..call error_get_last() function for err details.      
}

Few things to note:

If the destination file exists, copy will overwrite it. If you don't want this you can check the existence of the destination file using file_exists function before you copy.
Both the parameters of copy must be files. In Linux we usually do: cp file dir to copy the file file into the directory dir with the name file. This will not work with copy.
Some hosting companies disable copy function for security reasons. In that case you can implement your own copy by reading the file using file_get_contents and writing to the file using file_put_contents. Since you want to copy PHP scripts (which are not very large memory wise) this will work fine.
