create_initial_rest_routes()

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 create_initial_rest_routes() 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

Light

Touches nothing outside its own arguments.

Scaling

Scales with input

The body loops, so the work grows with how much data it finds.

Instructions

173–175

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 207.

Plugin surface

1 hook

Third-party callbacks on 'wp_rest_search_handlers' run inside this call, and their cost is not bounded by anything here.

Called by

0

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 create_initial_rest_routes() can have, taken from its control-flow graph on PHP 8.5.

Hooks and filters fired · 1

One hook fires while create_initial_rest_routes() runs, in this order:

1. 1
   apply_filters( wp_rest_search_handlers )filterline 342 (+77 into the body)

   Filters the search handlers to use in the REST search controller.
