I really wanted a read-eval-print-loop (repl) that I can use for learning PHP and tinkering with various parts of the language in isolation of a project’s codebase. I couldn’t find one online, so I built it.
It’s super simple and only took a couple of hours to create – which means that I didn’t spend much time worrying about sandboxing for security. The repl is secured by the hosting provider’s php configuration: removing access to the harmful functions. I’ve recently added another layer of blacklisted functions to the eval script. It should be pretty stable.
