Copying, Moving, and Deleting Files

 copy($filename, $tempname1); rename($tempname1, $tempname2); unlink($tempname2); 

Many other standard command-line functions of many operating systems are available in PHP. This not only includes chmod() and chgrp(), but also the following file system operations:

• copy() Copies a file

• rename() Moves a file

• unlink() Deletes a file

The preceding code duplicates the current file, moves it (or renames it), and finally deletes the resulting file.

Copying, Moving, and Deleting Files (copymovedelete.php)

 <?php   $filename = 'php.ini';   $tempname1 = $filename . rand();   $tempname2 = $filename . rand();   copy($filename, $tempname1);   echo "Copied to $tempname1<br />";   rename($tempname1, $tempname2);   echo "Moved to $tempname2<br />";   unlink($tempname2);   echo "File deleted."; ?>
