copy
Description
bool copy ( string source, string dest)
Makes a copy of the file
source
to
dest
. Returns
TRUE
on success or
FALSE
on failure. 
Example 1. copy() example
<?php
if (!copy($file, $file.'.bak')) {
echo "failed to copy $file...<br />\n";
}
?>
Note: As of PHP 4.3.0, both source and dest may be URLs if the "fopen wrappers" have been enabled. See fopen() for more details. If dest is a URL, the copy operation may fail if the wrapper does not support overwriting of existing files.
Warning
If the destination file already exists, it will be overwritten.
See also move_uploaded_file(), rename(), and the section of the manual about handling file uploads.
