how to include google analytics in php web service - php

Question

I have a webservice writen in php and it is called from an desktop application installed on PC's.
I want to have a register of the users who calls the functions on the web service and for this I only want to send hits to Google Analytics.
webservice in php:
<?php
require_once('lib/nusoap.php'); // basic include.. must go at the top
$SERVICE_NAMESPACE = "urn:Service"; // create a namespace to run under.
$server = new soap_server(); // the soap object from the include above.
// this has many input parameters but we only need two: the service name and the namespace
$server->configureWSDL('Service', $SERVICE_NAMESPACE);
$server->register('test',// method name
array('name' => 'xsd:string', 'name99' => 'xsd:string'),// input parameter called name.. and it's a string.
array('return' => 'xsd:string'),// output - one string is returned called "return"
$SERVICE_NAMESPACE,// namespace
$SERVICE_NAMESPACE . '#hello1',// soapaction
'rpc',// style.. remote procedure call
'encoded',// use of the call
'Nada interesante'// documentation for people who hook into your service.
);
function test($sName,$sName99)
{
return 'TEST ';
}
//This processes the request and returns a result.
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>
I want to have google analytics info and for that i want to integrate the following script:
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-89356985-1"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments)};
gtag('js', new Date());
gtag('config', 'UA-89356985-1');
</script>
I don't know how to integrate in the test function. I want to know when the users calls the test function.
Thanks in advance very much.

Answer 1

You cannot use the Javascript tracker unless your PHP script produces HTML and Javascript that is executed in a browser.
You can however use the Measurement Protocol to make server side calls to Google Analytics. That's basically an endpoint where you send predefined parameters with your custom values (via any method that can make http calls) and they will register in Google Analytics.

Answer 2

This can be used as en example of what you need. use http_build_queryto build you hit as you want to Google Analytics. Change Google_Analytics_UA_Stringto match your Google Analytics ID
<?php
//some of the functions we need to make it work
function generate_serial($n) {
$c = "abcdefghijklmnopqrstuvwyxz0123456789";
$s = '';
for($i=0;$i<$n;$i++) {
$s .= substr($c,rand(0,37),1);
}
return $s;
}
function generate_uuid() {
return generate_serial(8).'-'.generate_serial(4).'-4'.generate_serial(3).'-a'.generate_serial(3).'-'.generate_serial(12);
}
function ip() {
$ip = false;
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$ip = explode(',',$_SERVER['HTTP_X_FORWARDED_FOR']);
$ip = trim(array_shift($ip));
}
elseif(isset($_SERVER['REMOTE_ADDR'])) {
$ip = $_SERVER['REMOTE_ADDR'];
}
return $ip;
}
//define necessary variables
define('Google_Analytics_UA_String','UA-XXXXXXXX-X');
//create a UUID string for the user sending the request and store in the the session
if(isset($_COOKIE['Google_Analytics_UUID']) and !empty($_COOKIE['Google_Analytics_UUID'])) {
define('Google_Analytics_UUID',$_COOKIE['Google_Analytics_UUID']);
}
else {
define('Google_Analytics_UUID',generate_uuid());
setcookie('Google_Analytics_UUID',Google_Analytics_UUID,time()[phone]);
}
//compile the data we want to send to the API
$data = http_build_query(array(
'v' => 1, // version
'ds' => 'app', // data source
'tid' => Google_Analytics_UA_String, // Tracking ID / Web Property ID
'cid' => Google_Analytics_UUID, // Client ID
'uip' => ip(), // IP Override
't' => 'event', // Hit type
'ec' => 'site clicks', // event category
'ea' => 'click', // event action
'el' => 'button', // event label
'ev' => 'Click here!' // event value
));
//send using PHP's cURL extension
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,'https://www.google-analytics.com/collect');
curl_setopt($ch,CURLOPT_HEADER,true);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
$response = curl_exec($ch);
//parse the response and send back to the browser
header('Content-Type: application/json');
$status = curl_getinfo($ch,CURLINFO_HTTP_CODE);
if($status == 200) {
echo json_encode([
'success' => true
]);
}
else {
echo json_encode([
'error' => true
]);
}
?>

Answer 3

The exact running sample is:
<?php
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'http://www.google-analytics.com/collect?v=1&tid=UA-XXXXXXX-1&cid=35009a79-1a05-49d7-b876-2b884d0f825b&uid=myserid&uip=179.52.60.197&t=event&ec=Service&ea=SER&el=999999&z=54564653213',
CURLOPT_USERAGENT => 'Vanity-URL-Tracker',
));
$resp = curl_exec($curl);
curl_close($curl);
?>

Answer 4

I have an example for Page Tracking:
public function send($trackingId, $host, $page, $title)
{
$google_analytics_url = 'https://www.google-analytics.com/collect';
$google_analytics_params = http_build_query(array(
'v' => 1,
'tid' => $trackingId, // UA-xxxxxxx-x
'cid' => uniqid(),
't' => 'pageview',
'dh' => $host,
'dp' => '/'.$page,
'dt' => urlencode($title),
));
$url = $google_analytics_url.'?'.$google_analytics_params;
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $url,
CURLOPT_USERAGENT => 'Vanity-URL-Tracker',
));
$resp = curl_exec($curl);
$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);
if($status!= 200) {
log_message('error', json_encode(array('status' => $status, 'response' => $resp)) );
}
if (curl_errno($curl)) {
log_message('error', curl_error($curl));
}
curl_close($curl);
return $resp;
}
