Honestly, few people I know in the industry still use PHP. Internally, we only use it to handle some Drupal sites that we need to deprecate at some point. I'm working on a computer science degree with a focus on development. Started with Java, HTML/CSS/JS in first year. Second year is TS with a frontend framework (Angular and React), Python with some datascience libraries, Java Enterprise with Beans and Spring, C# with .NET Core and ASP.net. Last year we do mobile dev with Kotlin for Android and Swift for Apple. My stack is pretty wide.
