### Description
The following code:
```php
<?php
file_put_contents("./source", "bar");
file_put_contents("./dest", "foo");
$sourceHandle = fopen("./source", "r");
$destHandle = fopen("./dest", "a");
stream_copy_to_stream($sourceHandle, $destHandle);
fclose($sourceHandle);
fclose($destHandle);
echo ("foobar" === file_get_contents("./dest") ? "Ok" :
"KO");
```
Resulted in this output:
```
KO
```
But I expected this output instead:
```
Ok
```
