Luckily PHP pop has declined drastically since 2010. Its barely holding on as a top10 language. We can all hope it dies some day. We need better and faster software, realtime and unicode aware. We dont need more php.
Real numbers is hard to measure with PHP. This is because of the weird world of CMS systems (like wordpress). From all PHP code out there WordPress is most likely taking 80% of all the online deployments. So is it really PHP anymore? Its just a UI you click, drag and drop and customize. You dont even have to touch any code.
IF this is the measure, why not count PHP as C, as its written in C?
I stil argue that a single javascript library (jQuery) is MORE popular in 2025 than all PHP installations combined. Take that for scale. Now add all javascript (non compiled) and it trumps PHP by a factor of 100.
