GA E-Commerce tracking in PHP

Question

This is the code to send a purchase to Google Analytics E-Commerce tracking: it seems to be all right when executed on the debug URL

https://www.google-analytics.com/debug/collect

This is what the page returns:

{  
   "hitParsingResult":[  
      {  
         "valid":true,
         "parserMessage":[  

         ],
         "hit":"/debug/collect?v=1\u0026tid=UA-XXXXXXXX-X\u0026cid=XXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX\u0026t=event\u0026ti=UA-XXXXXXXX-X\u0026ta=test\u0026tr=1.00\u0026tt=0.22\u0026cu=EUR\u0026ts=0\u0026pa=purchase\u0026pr1id=ord690\u0026pr1nm=test prod\u0026pr1ca=test cat"
      }
   ],
   "parserMessage":[  
      {  
         "messageType":"INFO",
         "description":"Found 1 hit in the request."
      }
   ]
}

but it returns a 500 Error when executed on the regular URL

https://www.google-analytics.com/collect

I cannot understand what I'm missing.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

function generate_cid(){  

  $data = openssl_random_pseudo_bytes(16);    
  assert(strlen($data) == 16);  
  $data[6] = chr(ord($data[6]) & 0x0f | 0x40); //set version to 0100
  $data[8] = chr(ord($data[8]) & 0x3f | 0x80); //set bits 6-7 to 10 
  return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));

} // end generate_cid()

$data = array(
'v' => 1,
'tid' => 'UA-XXXXXXX-X',
'cid' => generate_cid(),
't' => 'event' 
);

$data['ti'] = "UA-XXXXXXXX-X";
$data['ta'] = "test";
$data['tr'] = "1.00";
$data['tt'] = "0.22";
$data['cu'] = "EUR";
$data['ts'] = "0";
$data['pa'] = "purchase";
$data['pr1id'] = "ord690";
$data['pr1nm'] = "test prod";
$data['pr1ca'] = "test cat";

//ONLY FOR DEBUG
//$url = 'https://www.google-analytics.com/debug/collect';

$url = 'https://www.google-analytics.com/collect':
$content = http_build_query($data);
$content = utf8_encode($content);
$user_agent = urlencode($_SERVER['HTTP_USER_AGENT']);

$ch = curl_init();
curl_setopt($ch,CURLOPT_USERAGENT, $user_agent);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_HTTPHEADER,array('Content-type: application/x-www-form-urlencoded'));
curl_setopt($ch,CURLOPT_HTTP_VERSION,CURL_HTTP_VERSION_1_1);
curl_setopt($ch,CURLOPT_POST, TRUE);
curl_setopt($ch,CURLOPT_POSTFIELDS, $content);
curl_exec($ch);
curl_close($ch);
?>

Print out whats in $url. The measurement protocol doesn't validate hits something else is wrong if your getting a 500 error. You should only utf8 the values not everything — DaImTo, Sep 25 '18 at 13:39

Thanks to @alberto, I find the easy mistake:

Colon instead of semicolon.

$url = 'https://www.google-analytics.com/collect';

After adding the code, we can see orders is coming into Google analytics however every order is attributed to the success page and "Direct" channel. Is there any way to fix this? – Piyush May 03 '21 at 10:39
