I'd suggest adjusting your text. Sure there is no subscription, but it's also not free. There's a one-time charge. I'm not against that - just saying it would be appropriate to be more transparent
I still love PHP. 23 years ago we created some encryption software for it and it is still going. I also run a PHP newsletter. There's still a strong community of people and whilst there are other languages which I also use (Python, Node.js) I still find myself gravitating towards PHP for fast and simple work
The only issues I have. is that this is a 'double edged sword' in that PHP has become far more complex since the launch of PHP 5 and so it isn't as easy to understand from scratch as it used to be
