PHP gets a lot of criticism for its legacy of behind hacked together. One thing that does get as much criticism, and one reason I avoid it for even simple things, is since it's request-based, it doesn't have a good story for connection pooling. While working on a former employer's PHP SDK, I had to add proxy hooks to it, then document how to set up Apache or Nginx as a proxy so you can get outbound connection pooling. If you depend on any third-party APIs, this can be a big deal for performance.
