Stream Component
================

[](#stream-component)

Provides RxPHP Observables for PHP streams

This library is a wrapper around the [ReactPHP](https://github.com/reactphp/stream) stream library. It uses the [Voryx event-loop](https://github.com/voryx/event-loop) which behaves like the Javascript event-loop. ie. You don't need to start it.

Usage
-----

[](#usage)

### From File

[](#from-file)

```

    $source = new \Rx\React\FromFileObservable("example.csv");

    $source
        ->cut() //Cut the stream by PHP_EOL
        ->map('str_getcsv') //Convert csv row to an array
        ->map(function (array $row) {
            //Strip numbers from the first field
            $row[0] = preg_replace('/\d+/u', '', $row[0]);
            return $row;
        })
        ->subscribe(
            function ($data) {
                echo $data[0] . "\n";
            },
            function ($e) {
                echo "error\n";
            },
            function () {
                echo "done\n";
            }
        );

```

### Read and Write to File

[](#read-and-write-to-file)

```
$source = new \Rx\React\FromFileObservable("source.txt");
$dest   = new \Rx\React\ToFileObserver("dest.txt");

$source
    ->cut()
    ->filter(function ($row) {
        return strpos($row, 'foo');
    })
    ->map(function ($row) {
        return $row . 'bar';
    })
    ->subscribe($dest);
```

### Stream - echo example

[](#stream---echo-example)

```
$read  = new \Rx\React\StreamSubject(STDIN);

$read
    ->takeWhile(function ($x) {
        return trim($x) != 15;
    })
    ->subscribe(new \Rx\React\StreamSubject(STDOUT));

```
