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 1.
Nothing here hands control to plugin code.
1 place in core call this, so the cost is paid more often than your own code shows.
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 get_shortcode_atts_regex() can have, taken from its control-flow graph on PHP 8.4.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 1 | none |
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
7.4 | 1 | 1 | 0 | Compiles to the same instructions |
8.1 | 1 | 1 | 0 | Compiles to the same instructions |
8.2 | 1 | 1 | 0 | Compiles to the same instructions |
8.3 | 1 | 1 | 0 | Compiles to the same instructions |
8.4 | 1 | 1 | 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.
