QR Code embedding in HTML using PHP

I have this code embedded in my HTML

<?php include "phpqrcode/qrlib.php";
$vcard = "BEGIN:VCARD\r\nVERSION:3.0\r\n
N:xyz; abc \r\n
FN: xyz abc \r\n
ORG:Example Organisation\r\n

URL;TYPE=work:www.example.com\r\n
EMAIL;TYPE=internet,pref:[email protected]\r\n

END:VCARD;";

QRcode::png($vcard);
?>

But when I run it i get an error

Warning: Cannot modify header information - headers already sent by (output started at
C:\xampp\htdocs\HMS_AmanVersion_1.1\getPatientData.php:165) in C:\xampp\htdocs\HMS_AmanVersion_1.1\phpqrcode\qrimage.php on line 35 ‰PNG IHDR««#&þZPLTEÿÿÿUÂÓ~µIDATH‰í–M®¥ …Ë0`† aÌØ’w^Ý€n‰Û aÞbõA_ç½tOº·1÷ç#Aë眂èÿõ÷52oÔÆTŽ ßLàSŽ ©ÝÈx>µ:=ˆ‡²&;ÄFÞ¾#Íz„#/d'­ÖJÓS¼Glj¹–-=ä6ïíOsàå;xîùöåûþQ†Ç}¥–EóÚˆ(ÿßñXÝžøŽûCxå<˱!Kš&íöØ^ýæCŽ‰Ô'¹3Šÿbk´Úà_©ÝˆúýNny€Q4íŽPNßÞ5Ϻ9"ac¤ù•ì˜ðW-rL(—Ï„.Žîƒœ'u>ÀPRm¯š ”Mî“Ú$ÇƗãòM„µ:§J†Qíë5(ÂÍ#»ãŽ×p®xMŒM=ÁÜç§vyÿ”cx&ÉÒ+_6XÎ¥u)¾zùvˆ>IÌo¯a¸æšÜàX8QZH|“ã~FFÇË5±Hyz€û¹ÕëdÚ³¾=Äje‹S˜ñ–áÑw…#òä6}÷ CCShÃuÜû¢#ß;óáZp¯yà6ËñÿëÏëPö8To±×1IEND®B

But if I run this file as an independent PHP file it runs and provides desired result. Any help?

Don't try to "embed" the png into your HMTL using PHP like that.

In HMTL use a normal image tag and set the SRC attribute to point to the PHP script which generates the image instead.

PHP: image.php

<?php
include "phpqrcode/qrlib.php";
$vcard =
    "BEGIN:VCARD\r\n".
    "VERSION:3.0\r\n".
    "N:xyz; abc\r\n".
    "FN: xyz abc\r\n".
    "ORG:Example Organisation\r\n".
    "URL;TYPE=work:www.example.com\r\n".
    "EMAIL;TYPE=internet,pref:[email protected]\r\n".
    "END:VCARD;";

QRcode::png($vcard);
?>

HTML: mypage.html

<img src="image.php" />
