WP_Recovery_Mode::handle_exit_recovery_mode()

Compatibility

Present in every tracked release (6.7.7 to 7.1.0), and compiles on PHP 7.4 through 8.6-dev.

Performance profile

How much work a call to WP_Recovery_Mode::handle_exit_recovery_mode() does, and what it touches: the algorithmic scaling, the Zend instruction count per call across PHP versions, the hooks it hands control to, and the core code that calls it. Measured from the compiled opcodes, not a stopwatch, so every number is identical on any machine running the same PHP version, and every function in core is ranked by cost.

Cost class

Trivial

Touches nothing outside its own arguments.

Scaling

Constant

No loop in the body: the same number of instructions runs whatever you pass in.

Instructions

11–62

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 66.

Plugin surface

None

Nothing here hands control to plugin code.

What it touches

• hookthird-party callbacksapply_filters()one call below WP_Recovery_Mode::handle_exit_recovery_mode()

Further down the call graph this can also reach option, cache, serialize, transient and query. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.

What one call costs · 42 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Recovery_Mode::handle_exit_recovery_mode() can have, taken from its control-flow graph on PHP 8.5.
