I have this opinion of PHP. I don't use it, and I look for alternatives when I find something that does what I want that's written in it.
Your callout is fair though. I'm not going to switch or anything. I'm happy with my favored scripting language. But I'll try to not be dismissive of projects that are written in PHP.
If you want to check some modern PHP code, you can check some pieces of mine (this project in particular could have a little cleaner code, but I think it demonstrates well what modern PHP can look like):
Your examples are ironically a great showcase of what I hate about PHP. Java-style object-obsessed programming with long names, piles of design patterns and dozens of imports, along with C-style syntax and dollars before variable names.
Java-style object-obsessed programming with long names
I mean, unlike Java, you can do procedural or functional (the support is getting better but I wouldn't call php the best language for functional). I personally love object-oriented design because it's the best (IMO) for large projects.
C-style syntax
That's a feature in my book, I almost exclusively write code in C-style languages and it's really easy switching between them. The only exception for me being Go.
dollars before variable names
That's just such a minor detail to hate language over. I like them (probably because PHP was my first language so I got used to them), but I don't quite care when I'm switching between languages.
