Reads stored settings via get_option(), cached per request but not free on a cold cache.
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.4, depending on the branch taken. The body compiles to 9.
Nothing here hands control to plugin code.
Nothing in core calls this; the cost is only what you spend yourself.
What it touches
- optionoption read or write
get_option()one call below wp_robots_noindex_embeds()
Further down the call graph this can also reach hook, cache, serialize, query 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 · 2 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_robots_noindex_embeds() can have, taken from its control-flow graph on PHP 8.4.

Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
7.4 | 9 | 5–8 | 1 | Compiles to the same instructions |
8.1 | 9 | 5–8 | 1 | Compiles to the same instructions |
8.2 | 9 | 5–8 | 1 | Compiles to the same instructions |
8.3 | 9 | 5–8 | 1 | Compiles to the same instructions |
8.4 | 9 | 5–8 | 1 | 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.
