php 한글 메뉴얼 도움말 검색 사이트 Copies file [function.copy]

bool copy ( string $source , string $dest [, resource $context ] )

Makes a copy of the file source to dest.

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

source: Path to the source file.
dest: The destination path. 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.
context: A valid context resource created with stream_context_create().

성공 시 TRUE를, 실패 시 FALSE를 반환합니다.

버전	설명
5.3.4	Changed the `context` parameter to actually have an effect. Previously, any `context` was ignored.
5.3.0	Added context support.
4.3.0	Both `source` and `dest` may now be URLs if the "fopen wrappers" have been enabled. See fopen() for more details.

Example #1 copy() example


<?php
$file = 'example.txt';
$newfile = 'example.txt.bak';

if (!copy($file, $newfile)) {
    echo "failed to copy $file...\n";
}
?>
