# runNonBlocking()

Runs a new coroutine and **non-blocks** the current thread. This static function should not be used from a coroutine.

```php
CoroutineGen::runNonBlocking(
    function() : \Generator {
        $return = yield file_get_contents('http://www.weather.com.cn/data/cityinfo/101270101.html');
        var_dump($return);
    },
    function() : \Generator {
        yield var_dump("END!");
    },
    function() {
        var_dump("START!");
    },
    function() {
        var_dump("Hello World!");
    }
);
```

Output:

```
string(6) "START!"
string(12) "Hello World!"
string(10989) "<!DOCTYPE HTML>
<html>
<head> ...."

string(4) "END!"
```

Example other:

```php
function a() {
    for ($i = 0; $i <= 5; $i++) {
        yield var_dump("A");
    }
}

function b() {
    for ($i = 0; $i <= 5; $i++) {
        yield var_dump("B");
    }
}

CoroutineGen::runNonBlocking(
    a(),
    b(),
    function() {
        var_dump("C");
    }
);

var_dump("Running after coroutines");
```

Output:

```
string(1) "C"
string(1) "A"
string(1) "A"
string(1) "B"
string(1) "B"
string(1) "A"
string(24) "Running after coroutines"
string(1) "B"
string(1) "A"
string(1) "B"
string(1) "A"
string(1) "B"
string(1) "A"
string(1) "B"
```
