（内置）Requests 类允许您同时调用多个请求：Requests::request_multiple.

<?php

$requests = Requests::request_multiple([
    [
        \'url\' => \'https://www.mocky.io/v2/5acb821f2f00005300411631\',
        \'type\' => \'GET\',
        \'headers\' => [
            \'Accept\' => \'application/json\'
        ],

    ],
    [
        \'url\' => \'https://www.mocky.io/v2/5acb821f2f00005300411631\',
        \'type\' => \'POST\',
        \'headers\' => [
            \'Accept\' => \'application/json\'
        ],
        \'data\' => json_encode([
            \'text\' => \'My POST Data\'
        ])
    ],
    [
        \'url\' => \'https://www.mocky.io/v2/5acb82ee2f00005100411635\',
        \'type\' => \'POST\',
        \'headers\' => [
            \'Accept\' => \'application/json\'
        ],
        \'data\' => json_encode([
            \'text\' => \'More POST Data\'
        ])
    ],  
]);

foreach ($request as $request) {
    if ($request->status_code !== 200) {
        // handle error
    }
    // handle success
    echo $request->body;
}
