Reads or writes the filesystem via file_get_contents().
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 7.
Nothing here hands control to plugin code.
Nothing in core calls this; the cost is only what you spend yourself.

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 WP_Filesystem_Direct::get_contents() can have, taken from its control-flow graph on PHP 8.4.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 7 | file_get_contents() |
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
7.4 | 7 | 7 | 0 | Compiles to the same instructions |
8.1 | 7 | 7 | 0 | Compiles to the same instructions |
8.2 | 7 | 7 | 0 | Compiles to the same instructions |
8.3 | 7 | 7 | 0 | Compiles to the same instructions |
8.4 | 7 | 7 | 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.
