Hi @Kevin Dule ,
We have this sample for B2C integration into a PHP/Laravel app. The sample is deprecated and there hasn't been a new version released yet, but you can reference it for your project. https://github.com/Azure-Samples/active-directory-b2c-php-webapp-openidconnect/blob/main-deprecated/README.md#php-web-application-with-azure-ad-b2c
There's also a marketplace sample here, though it appears to have been submitted by a third party user so I cannot speak to it.
If you would like to request more samples, you can do so under the project itself or in the feedback forum. I'm also happy to relay your request to some of my colleagues. https://feedback.azure.com/
