Both of the examples should work perfectly fine if you're using the dev-main branch. Without knowing anything about your code or setup it's hard to remote-diagnose. The error says that the given class is not valid, which should not happen if you ran the unmodified examples you linked. If nothing helps, try cloning the library, run composer install in the library root and try running the examples.

yes i used library with Laravel, Normally working. Just Your given Code not working wit Laravel.

Here i use Core PHP and i able to generate with your given code, but with error. Here is heart in QrCode i dont want heart in code. I try but i unable to fix that.

Actually I want to generate QRCode Same Like This.

Many people use this library with Laravel and i haven't heard yet that it isn't working. Still, i don't see any of your code and what you're trying to do and how. I cannot help you this way.

This is my Laravel Controller
Edited: I updated my code here.

Ahh, now we're getting closer. The problem is that your classes do not adhere to the PSR-4 autoloading standard. The example is self-contained so that it can be run to try things out without hassle. But if you want to include it in your project, you have to split it up and put each class in its own file, with the class name being the file name: QRSvgWithLogoAndCustomShapes.php -> class QRSvgWithLogoAndCustomShapes{} and so on. Additionally, the classes are supposed to reside in your project, with a namespace that matches your directory structure.

[shoaib039]

Thank you very Much. I did same as what you told me to do, now QrCode Generating fine. And i also Modified Source as per my Requiremets. And just one thing left, There is Circle eye in QrCode but i want rounded.

Generated QrCode Eye is in circle form.

I want Like this

Please help me to modify Code :)

[codemasher]

I'm pretty sure that you can figure this out in the same way i had to figure it out. There's the exact shape you need already in this example SVG. All you need to do is to size it up so that it fits into the path in the getFinderPatterns() method and replace the 2 half circles.
There are also several tutorials and docs listed in the SVG output class:

• https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/d
• http://apex.infogridpacific.com/SVG/svg-tutorial-path-intro.html#Lesson15
