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.
