As someone who maintains an extension for PHP, I hate it because the Zend C APIs are an undocumented dumpster fire, and PHP's basic data structure, zend_hash, is a weird hash type with a str/int union key type and an awkward API. I also hate it because I hit more memory issues (double free, unitialized reads, etc.) in the language and core libs with PHP than any other high level language I'm maintaining similar extensions for.
