# copy

(PHP 3, PHP 4 , PHP 5)

copy -- Copies file

## Description

bool copy ( string source, string dest)

Makes a copy of the file source to dest. 成功回傳`TRUE`失敗回傳`FALSE`。

示範 1.copy() example
`<?php if (!copy($file, $file.'.bak')) { echo "failed to copy $file...<br />\n"; } ?>`

If you wish to move a file, use the rename() function.

> 備注: 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.

切記!
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.
