Subtle genius at work here. In PHP, all variables start with a dollar sign ($), but the joke pretends it's because PHP developers are desperately chasing money rather than just following syntax rules. Meanwhile, JavaScript developers are over here using camelCase like they're riding economic humps to prosperity, and Python devs think whitespace will somehow pay their bills. The irony? PHP powers ~78% of the web, including Facebook, which literally prints money. So maybe those dollar signs were prophetic after all.
