WP_Site_Health::get_test_autoloaded_options(): array

Compatibility

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

Return value

array

The test results.

Performance profile

How much work a call to WP_Site_Health::get_test_autoloaded_options() 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

Only touches the object cache, via wp_cache_get().

Scaling

Constant

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

Instructions

51–110

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 111.

Plugin surface

3 hooks

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

Nothing in core calls this; the cost is only what you spend yourself.

What it touches

• hookthird-party callbacksapply_filters()called directly
• cacheobject cachewp_cache_get()one call below WP_Site_Health::get_test_autoloaded_options()

Further down the call graph this can also reach option, serialize, 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 · 2 distinct outcomes

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

Hooks and filters fired · 3
