file_unmanaged_move($source, $destination = NULL, $replace = FILE_EXISTS_RENAME)
Moves 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 rename().
- Checks if $source and $destination are valid and readable/writable.
- Checks that $source is not equal to $destination; if they are an error is reported.
- If file already exists in $destination either the call will error out, replace the file or rename the file based on the $replace parameter.
- Works around a PHP bug where rename() 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 moved to. The URI may be a bare filepath (without a scheme) and in that case the default scheme (file://) will be used. 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.
