1. 9 core/modules/file/file.module \file_move()
2. 8.9.x core/modules/file/file.module \file_move()

Moves a file to a new location and update the file's database entry.

Moving a file is performed by copying the file to the new location and then deleting the original.

• Checks if $source and $destination are valid and readable/writable.
• Performs a file move if $source is not equal to $destination.
• If file already exists in $destination either the call will error out, replace the file or rename the file based on the $replace parameter.
• Adds the new file to the files database.

Parameters

$source: A file object.

$destination: A string containing the destination that $source should be moved to. This must be a stream wrapper URI.

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

• FILE_EXISTS_REPLACE - Replace the existing file. If a managed file with the destination name exists then its database entry will be updated and file_delete() called on the source file after hook_file_move is called. If no database entry is found then the source files record will be updated.
• FILE_EXISTS_RENAME - Append _{incrementing number} until the filename is unique.
• FILE_EXISTS_ERROR - Do nothing and return FALSE.

Return value

Resulting file object for success, or FALSE in the event of an error.
