# Websocket: Messages
|
||
|
|
||
|
If option `return_obj` is set to `true` on [client](Client.md) or [server](Server.md),
|
||
|
the `receive()` method will return a Message instance instead of a string.
|
||
|
|
||
|
Available classes correspond to opcode;
|
||
|
* WebSocket\Message\Text
|
||
|
* WebSocket\Message\Binary
|
||
|
* WebSocket\Message\Ping
|
||
|
* WebSocket\Message\Pong
|
||
|
* WebSocket\Message\Close
|
||
|
|
||
|
Additionally;
|
||
|
* WebSocket\Message\Message - abstract base class for all messages above
|
||
|
* WebSocket\Message\Factory - Factory class to create Message instances
|
||
|
|
||
|
## Message abstract class synopsis
|
||
|
|
||
|
```php
|
||
|
WebSocket\Message\Message {
|
||
|
|
||
|
public __construct(string $payload = '');
|
||
|
public __toString() : string;
|
||
|
|
||
|
public getOpcode() : string;
|
||
|
public getLength() : int;
|
||
|
public getTimestamp() : DateTime;
|
||
|
public getContent() : string;
|
||
|
public setContent(string $payload = '') : void;
|
||
|
public hasContent() : bool;
|
||
|
}
|
||
|
```
|
||
|
|
||
|
## Factory class synopsis
|
||
|
|
||
|
```php
|
||
|
WebSocket\Message\Factory {
|
||
|
|
||
|
public create(string $opcode, string $payload = '') : Message;
|
||
|
}
|
||
|
```
|
||
|
|
||
|
## Example
|
||
|
|
||
|
Receving a Message and echo some methods.
|
||
|
|
||
|
```php
|
||
|
$client = new WebSocket\Client('ws://echo.websocket.org/', ['return_obj' => true]);
|
||
|
$client->text('Hello WebSocket.org!');
|
||
|
// Echo return same message as sent
|
||
|
$message = $client->receive();
|
||
|
echo $message->getOpcode(); // -> "text"
|
||
|
echo $message->getLength(); // -> 20
|
||
|
echo $message->getContent(); // -> "Hello WebSocket.org!"
|
||
|
echo $message->hasContent(); // -> true
|
||
|
echo $message->getTimestamp()->format('H:i:s'); // -> 19:37:18
|
||
|
$client->close();
|
||
|
```
