php - 从本地主机到实时站点的 Curl 响应不一致

Question

大家好，我有一个 php 文件，它返回一个 JSON，这是我根据curl 的响应构建的。我的问题是，当我在本地(localhost)服务器中运行它时，JSON 响应的长度是 55，这是正确的，它获得了我需要的所有事件。但是当我在我们的托管站点上尝试时，响应不一致，它与本地主机不同。对于第一次加载，我检查了长度响应，它返回了 55 个事件中的 32 个，然后我尝试再次重新加载它，然后响应增加到 39 等等。

这是我的本地主机响应。 [https://prnt.sc/rll4w0] 。这是 cpanel https://cdev.trilogycap.co/icedev/dynamic/civicore.php 上托管的文件.这是第一个回复https://prnt.sc/rll2rc .当我再次重新加载此页面时 https://prnt.sc/rll3fl

我的php文件函数流程是这样的。我有一个函数可以获取今年事件的所有 ID 并将其推送到全局数组。我已经删除了那里重复的 ID。所以现在我调用一个 multicurl 函数。

其中，对于每个ID，我将再次处理并调用API并构建它。然后，我将其推送到全局的 responseEvents 变量数组中，然后对其进行编码，以便能够生成有效的 JSON 文件。我在多 curl 中做了什么连接或错误的事情吗？它们是 php multi curl 的执行限制吗？或者 settimelimit(0) 会影响我的代码吗？

这是我的代码

<?php
//Use this so that when we run the curl it wont timeout when dealing with getting data
set_time_limit(0);
$API_KEY  = "APIKEY";
$CURRENT_YEAR = date("Y");
$CURRENT_MONTH = date("m");
$CURRENT_DAY = date("d");
$events = getOpportunityYearly();//array of ID's removed duplicates [1,1,2,3,4,5 etc]
$noDuplicate =  array_values(array_unique($events));//remove $event ID duplciates
$responseEvents = [];//this is the array to be returned as json to use

//pass noDuplicate array which holds event ID's
multiCurl($noDuplicate);
print_r(json_encode($responseEvents, JSON_HEX_QUOT |  JSON_HEX_TAG | JSON_HEX_AMP |JSON_UNESCAPED_SLASHES ));

//returns an array of ID of events

  $eventArr = [];//pass eventsID here

我认为不知何故，你的curl在输入这个foreach时没有检索所有信息foreach($multiCurl as $key=>$value)这可以解释为什么它在本地(快速响应)上可以，而不是在远程服务器上(网络时间，响应时间更长)。

你应该试试这个，这是我从 documentation 得到的并且应该等待所有连接正确结束。

do {
    $status = curl_multi_exec($mh, $index);
    if ($index) {
        // Wait a short time for more activity
        curl_multi_select($mh);
    }
} while ($index && $status == CURLM_OK);
