swoole_client的实现源码主要在swoole-src/swoole_client.c中。

swoole_client有同步和异步两种使用方式，如下：

<?php
$client = new swoole_client(SWOOLE_SOCK_TCP);
if (!$client->connect('127.0.0.1', 9501, 0.5))
{
    die("connect failed.");
}

if (!$client->send("hello world"))
{
    die("send failed.");
}

$data = $client->recv();
if (!$data)
{
    die("recv failed.");
}

$client->close();

<?php
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);

$client->on("connect", function($cli) {
    $cli->send("hello world\n");
});
$client->on("receive", function($cli, $data){
    echo "Received: ".$data."\n";
});
$client->on("error", function($cli){
    echo "Connect failed\n";
});
$client->on("close", function($cli){
    echo "Connection close\n";
});

$client->connect('127.0.0.1', 9501, 0.5);
