UploadedFileInterface:: (6 methods):
  getStream()
  moveTo()
  getSize()
  getError()
  getClientFilename()
  getClientMediaType()


Interface: UploadedFileInterface  - X-Ref

Value object representing a file uploaded through an HTTP request.

Instances of this interface are considered immutable; all methods that
might change state MUST be implemented such that they retain the internal
state of the current instance and return an instance that contains the
changed state.
getStream()   X-Ref
Retrieve a stream representing the uploaded file.

This method MUST return a StreamInterface instance, representing the
uploaded file. The purpose of this method is to allow utilizing native PHP
stream functionality to manipulate the file upload, such as
stream_copy_to_stream() (though the result will need to be decorated in a
native PHP stream wrapper to work with such functions).

If the moveTo() method has been called previously, this method MUST raise
an exception.

return: StreamInterface Stream representation of the uploaded file.

moveTo($targetPath)   X-Ref
Move the uploaded file to a new location.

Use this method as an alternative to move_uploaded_file(). This method is
guaranteed to work in both SAPI and non-SAPI environments.
Implementations must determine which environment they are in, and use the
appropriate method (move_uploaded_file(), rename(), or a stream
operation) to perform the operation.

$targetPath may be an absolute path, or a relative path. If it is a
relative path, resolution should be the same as used by PHP's rename()
function.

The original file or stream MUST be removed on completion.

If this method is called more than once, any subsequent calls MUST raise
an exception.

When used in an SAPI environment where $_FILES is populated, when writing
files via moveTo(), is_uploaded_file() and move_uploaded_file() SHOULD be
used to ensure permissions and upload status are verified correctly.

If you wish to move to a stream, use getStream(), as SAPI operations
cannot guarantee writing to stream destinations.

param: string $targetPath Path to which to move the uploaded file.

getSize()   X-Ref
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.

return: int|null The file size in bytes or null if unknown.

getError()   X-Ref
Retrieve the error associated with the uploaded file.

The return value MUST be one of PHP's UPLOAD_ERR_XXX constants.

If the file was uploaded successfully, this method MUST return
UPLOAD_ERR_OK.

Implementations SHOULD return the value stored in the "error" key of
the file in the $_FILES array.

return: int One of PHP's UPLOAD_ERR_XXX constants.

getClientFilename()   X-Ref
Retrieve the filename sent by the client.

Do not trust the value returned by this method. A client could send
a malicious filename with the intention to corrupt or hack your
application.

Implementations SHOULD return the value stored in the "name" key of
the file in the $_FILES array.

return: string|null The filename sent by the client or null if none

getClientMediaType()   X-Ref
Retrieve the media type sent by the client.

Do not trust the value returned by this method. A client could send
a malicious media type with the intention to corrupt or hack your
application.

Implementations SHOULD return the value stored in the "type" key of
the file in the $_FILES array.

return: string|null The media type sent by the client or null if none
