# 在php-fpm或apache中使用swoole swoole中绝大部分的模块只能用于`CLI命令行`环境，只有同步阻塞的`swoole_client`可以用于`php-fpm`或`apache`环境。 ## 同步swoole\_client ~~~ $client = new swoole_client(SWOOLE_SOCK_TCP); //同步阻塞 $client->connect('127.0.0.1', 9501) or die("connect failed\n"); $client->send(str_repeat("A", 600)); $data = $client->recv(700, 0) or die("recv failed\n"); echo "recv: " . $data . "\n"; ~~~
