第三方Google Analytics sdk问题

Question

我的代码在php 5之上工作

它实际上是GA库，这是它的github项目。

我克隆了项目theiconic/php-ga-measurement-protocol

由于我是PHP的新手，我不知道在哪里放这个代码，请在这里帮助我这个项目应该通过编码器通过代码安装

{
    "require": {
        "theiconic/php-ga-measurement-protocol": "^2.0"
    }
}

在这一步之后，我需要创建一个文件something.php，我需要把代码放在下面，我在服务器上找到autoload.php时遇到问题，请看下面的代码来理解我在说什么。

<?php
        //grab the data that Calendly sent in the webhook and store it in a variable called $objCalendlySubmission...
        $objCalendlySubmission = json_decode(file_get_contents('php://input'));

        //We've passed the Google client_id in Calendly's placeholder for utm_term. Feel free to pass it differently, this is just an example
        if(property_exists($objCalendlySubmission->payload->tracking, 'utm_term') && !empty($objCalendlySubmission->payload->tracking->utm_term)) {
            $strPageViewed = 'calendly_conversion.html'; // We use different page names depending on what type of event was scheduled via Calendly
            sendGoogleAnalyticsPageView($objCalendlySubmission->payload->tracking->utm_term, $strPageViewed);
        }

        function sendGoogleAnalyticsPageView($strGAClientId, $strURL) {
            require_once '/path_to_composer/composer/vendor/autoload.php'; //loads the PHP library for the "Google Analytics Measurement Protocol” **I dont know where is it located exactly on my xampp server, Please guide me here**
            $analytics = new TheIconic\Tracking\GoogleAnalytics\Analytics(true); //you may have to adjust this path based on your setup **please help me here**

            $analytics
                ->setProtocolVersion('1')
                ->setTrackingId('YOUR-GA-UA-ID-GOES-HERE')
                ->setClientId($strGAClientId)
                ->setDocumentLocationUrl($strURL);

            $analytics->sendPageview(); 
        }
        ?>

在上面的代码中间

require_once '/path_to_composer/composer/vendor/autoload.php'; //loads the PHP library for the "Google Analytics Measurement Protocol” 

我不知道它在xampp服务器上的位置，请指导我

$analytics = new TheIconic\Tracking\GoogleAnalytics\Analytics(true); //you may have to adjust this path based on your setup
