Performance profile
How much work a call to wp_get_sidebars_widgets() 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.

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 8.5, depending on the branch taken. The body compiles to 36.
Third-party callbacks on 'sidebars_widgets' run inside this call, and their cost is not bounded by anything here.
18 places in core call this, so the cost is paid more often than your own code shows.
What it touches
- optionoption read or write
get_option()called directly - hookthird-party callbacks
apply_filters()called directly - cacheobject cache
wp_cache_get()one call below wp_get_sidebars_widgets() - serializeserialisation
maybe_unserialize()one call below wp_get_sidebars_widgets()
Further down the call graph this can also reach 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 · 4 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_get_sidebars_widgets() can have, taken from its control-flow graph on PHP 8.5.
| When | Instructions | Calls it makes |
|---|---|---|
$deprecated is not null, false, long, double, string, array, object, resource && !is_admin() && !empty($_wp_sidebars_widgets) | 19–22 | is_admin(), apply_filters() |
$deprecated is not null, false, long, double, string, array, object, resource | 20–27 | is_admin(), get_option(), apply_filters() |
$deprecated is null, false, long, double, string, array, object, resource && !is_admin() && !empty($_wp_sidebars_widgets) | 23–26 | _deprecated_argument(), is_admin(), apply_filters() |
$deprecated is null, false, long, double, string, array, object, resource | 24–31 | _deprecated_argument(), is_admin(), get_option(), apply_filters() |
Across PHP versions
Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 36 instructions, 19–31 executed per call, 5 branches. The work does not change between versions.
An instruction is not a fixed amount of time, so a matching count is not necessarily the same speed; what it rules out is a difference in the work itself.
