1. 7.x includes/file.inc \file_unmanaged_copy()

Copies a file to a new location without database changes or hook invocation.

This is a powerful function that in many ways performs like an advanced version of copy().

• Checks if $source and $destination are valid and readable/writable.
• If file already exists in $destination either the call will error out, replace the file or rename the file based on the $replace parameter.
• If the $source and $destination are equal, the behavior depends on the $replace parameter. FILE_EXISTS_REPLACE will error out. FILE_EXISTS_RENAME will rename the file until the $destination is unique.
• Works around a PHP bug where copy() does not properly support streams if safe_mode or open_basedir are enabled.

Parameters

$source: A string specifying the filepath or URI of the source file.

$destination: A URI containing the destination that $source should be copied to. The URI may be a bare filepath (without a scheme). If this value is omitted, Drupal's default files scheme will be used, usually "public://".

$replace: Replace behavior when the destination file already exists:

• FILE_EXISTS_REPLACE - Replace the existing file.
• FILE_EXISTS_RENAME - Append _{incrementing number} until the filename is unique.
• FILE_EXISTS_ERROR - Do nothing and return FALSE.

Return value

The path to the new file, or FALSE in the event of an error.
