WP_Site_Health::get_test_http_requests(): array
- Since
- 5.2.0
- Source
wp-admin/includes/class-wp-site-health.php:2051
Description
It's possible to block all outgoing communication (with the possibility of allowing certain hosts) via the HTTP API. This may create problems for users as many features are running as services these days.
Compatibility
- WordPress
- since 5.2.0
- PHP
- 7.4–8.6-dev
- 6.7.7
- 6.8.8
- 6.9.7
- 7.0.4

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_http_requests() 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.

Touches nothing outside its own arguments.
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 85.
Nothing here hands control to plugin code.
Nothing in core calls this; the cost is only what you spend yourself.
What one call costs · 6 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_http_requests() can have, taken from its control-flow graph on PHP 8.5.

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.
