* Doesn't close the underlying stream when 'close' is called on it. Instead, |
15
|
|
|
* calling close simply removes any reference to the underlying stream. Note |
16
|
|
|
* that GuzzleHttp\Psr7\Stream calls close in __destruct, so a reference to the |
17
|
|
|
* Stream needs to be kept. For example: |
18
|
|
|
* |
19
|
|
|
* ``` |
20
|
|
|
* $f = fopen('php://temp', 'r+'); |

* // work |
23

|
|
* $test->close(); |
24
|
|
|
* rewind($f); // error, $f is a closed resource |
25

|
|
* ``` |
26

29
