wp_sensitive_page_meta()

Since
5.0.1
Source
wp-includes/deprecated.php:4205
Display a noindex,noarchive meta tag and referrer strict-origin-when-cross-origin meta tag.

Description

Outputs a noindex,noarchive meta tag that tells web robots not to index or cache the page content.
Outputs a referrer strict-origin-when-cross-origin meta tag that tells the browser not to send the full URL as a referrer to other sites when cross-origin assets are loaded.

Typical usage is as a 'wp_head' callback:

add_action( 'wp_head', 'wp_sensitive_page_meta' );

Compatibility

Deprecated in WordPress 5.7.0. Use wp_robots_sensitive_page() instead on 'wp_robots' filter and wp_strict_cross_origin_referrer() on 'wp_head' action.

Performance profile

How much work a call to wp_sensitive_page_meta() 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
Trivial

Touches nothing outside its own arguments.

Scaling
Constant

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

Instructions
9

Executed per call on PHP 8.5. The body compiles to 9.

Plugin surface
None

Nothing here hands control to plugin code.

Called by
0

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

What it touches

  • hookthird-party callbacksdo_action()one call below wp_sensitive_page_meta()

Further down the call graph this can also reach query, option, cache, serialize 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 · 1 distinct outcome

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

WhenInstructionsCalls it makes
always9_deprecated_function(), wp_strict_cross_origin_referrer()

Across PHP versions

Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 9 instructions, 9 executed per call, 0 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.
