File.php

Run our SplFileInfo constructor with an optional verification that the path is really a file.

Retrieve the file size. Implementations SHOULD return the value stored in the "size" key of the file in the $_FILES array if available, as PHP calculates this based on the actual size transmitted. A RuntimeException will be thrown if the file does not exist or an error occurs.

Retrieve the file size by unit, calculated in IEC standards with 1024 as base value.

Retrieve the file size by unit, calculated in metric standards with 1000 as base value.

Retrieve the file size by unit.

Attempts to determine the file extension based on the trusted getType() method. If the mime type is unknown, will return null.

Retrieve the media type of the file. SHOULD not use information from the $_FILES array, but should use other methods to more accurately determine the type of file, like finfo, or mime_content_type().

Generates a random names based on a simple hash and the time, with the correct file extension attached.

Moves a file to a new location.

Returns the destination path for the move operation where overwriting is not expected. First, it checks whether the delimiter is present in the filename, if it is, then it checks whether the last element is an integer as there may be cases that the delimiter may be present in the filename. For the all other cases, it appends an integer starting from zero before the file's extension.
