Touches nothing outside its own arguments.
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.4. The body compiles to 10.
Third-party callbacks on 'comment_text_rss' run inside this call, and their cost is not bounded by anything here.
Nothing in core calls this; the cost is only what you spend yourself.

Further down the call graph this can also reach option, query, cache, serialize and transient — those are the worst case, several calls deep and usually down an error path, not what a normal call pays.
What one call costs · 1 distinct outcome
One number would be a lie: the work depends on which branch runs. These are every distinct cost comment_text_rss() can have, taken from its control-flow graph on PHP 8.4.

Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
7.4 | 10 | 10 | 0 | Compiles to the same instructions |
8.1 | 10 | 10 | 0 | Compiles to the same instructions |
8.2 | 10 | 10 | 0 | Compiles to the same instructions |
8.3 | 10 | 10 | 0 | Compiles to the same instructions |
8.4 | 10 | 10 | 0 | Compiles to the same instructions |
Oldest PHP that compiles this body: 7.4. An instruction is not a fixed amount of time, so a version with the same count is not necessarily the same speed; what the count rules out is a difference in the work itself.
