# php-tokio example
|
|
|
|
Here's a usage example of [php-tokio](https://github.com/danog/php-tokio/), using the async Rust [reqwest](https://docs.rs/reqwest/latest/reqwest/) library to make asynchronous HTTP requests from PHP:
|
|
|
|
```php
|
|
<?php
|
|
|
|
use Reqwest\Client;
|
|
|
|
use function Amp\async;
|
|
use function Amp\Future\await;
|
|
|
|
require 'vendor/autoload.php';
|
|
|
|
Client::init();
|
|
|
|
function test(int $delay): void {
|
|
$url = "https://httpbin.org/delay/$delay";
|
|
$t = time();
|
|
echo "Making async reqwest to $url that will return after $delay seconds...".PHP_EOL;
|
|
Client::get($url);
|
|
$t = time() - $t;
|
|
echo "Got response from $url after ~".$t." seconds!".PHP_EOL;
|
|
};
|
|
|
|
$futures = [];
|
|
$futures []= async(test(...), 5);
|
|
$futures []= async(test(...), 5);
|
|
$futures []= async(test(...), 5);
|
|
|
|
await($futures);
|
|
```
|
|
|
|
Usage:
|
|
|
|
```bash
|
|
cd examples/reqwest && \
|
|
cargo build && \
|
|
composer update && \
|
|
php -d extension=../../target/debug/libexample_reqwest.so test.php
|
|
```
|
|
|
|
Result:
|
|
|
|
```
|
|
Making async reqwest to https://httpbin.org/delay/5 that will return after 5 seconds...
|
|
