PHP
A programming language built specifically for the web, powering a large share of the internet's backends (including WordPress) — older and less trendy than newer languages, but still extremely widely deployed.
Think of it like
Like an older but massively common home wiring standard — not what a new build would choose today, but the majority of existing houses run on it.
Junior or senior?
Junior sounds like
Worked in old-style untyped, procedural PHP.
Senior sounds like
Worked in modern PHP (7.4+/8), typed and framework-based — a meaningfully different job.
Ask them
“Is your PHP experience with a modern version and framework, or older procedural-style PHP?”
