wp_ajax_toggle_auto_updates()

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_ajax_toggle_auto_updates() 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

Moderate

Reads stored settings via get_site_option(), cached per request but not free on a cold cache.

Scaling

Constant

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

Instructions

71–125

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 158.

Plugin surface

1 hook

Third-party callbacks on 'all_plugins' 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.

• optionnetwork optionget_site_option()called directly
• cacheobject cachewp_cache_get()one call below wp_ajax_toggle_auto_updates()

Further down the call graph this can also reach transient, serialize 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 · 112 distinct outcomes

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