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. Returns TRUE on success or FALSE on failure.

Example 1. copy() example

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

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

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

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.

Note: Windows compatibility: If you copy a file with no size, copy() will return FALSE, but the file will be correctly copied.

See also move_uploaded_file(), rename(), and the section of the manual about handling file uploads.
