UploadedFileInterface
in
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.

Methods
getClientFilename()
Retrieve the filename sent by the client.
public
getClientFilename() : string|null
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 values
string|null —The filename sent by the client or null if none was provided.
getClientMediaType()
Retrieve the media type sent by the client.
public
getClientMediaType() : string|null
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 values
string|null —The media type sent by the client or null if none was provided.
getError()
Retrieve the error associated with the uploaded file.
public
getError() : int
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.
Tags
Return values
int —One of PHP's UPLOAD_ERR_XXX constants.
getSize()
Retrieve the file size.
public
getSize() : int|null
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 values
int|null —The file size in bytes or null if unknown.
getStream()
Retrieve a stream representing the uploaded file.
public
getStream() : StreamInterface
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.
Tags
Return values
StreamInterface —Stream representation of the uploaded file.
moveTo()
Move the uploaded file to a new location.
public
moveTo(string $targetPath) : void
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.
Parameters
- $targetPath : string
-
Path to which to move the uploaded file.
