wp_cookie_constants()

Since
3.0.0
Source
wp-includes/default-constants.php:243
Defines cookie-related WordPress constants.

Description

Defines constants after multisite is loaded.

Compatibility

WordPress
since 3.0.0
PHP
7.4–8.6-dev
  • 6.7.7
  • 6.8.8
  • 6.9.7
  • 7.0.4
  • 7.1.0

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_cookie_constants() 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
27–92

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 112.

Plugin surface
None

Nothing here hands control to plugin code.

0

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

What it touches

  • optionnetwork optionget_site_option()called directly
  • hookthird-party callbacksapply_filters()one call below wp_cookie_constants()
  • cacheobject cachewp_cache_get()one call below wp_cookie_constants()
  • serializeserialisationmaybe_unserialize()one call below wp_cookie_constants()

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 · 53 distinct outcomes

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

This body has more branch combinations than are worth enumerating, so the table covers the outcomes found first rather than every one that exists.

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.

Uses · 2

  • get_site_option()Retrieve an option value for the current network based on name of option.
  • get_option()Retrieves an option value based on an option name.
