wp_filter_out_block_nodes( $nodes ): array<array<string,

Since
6.1.0
Source
wp-includes/script-loader.php:2544
Applies a filter to the list of style nodes that comes from WP_Theme_JSON::get_style_nodes().

Description

This particular filter removes all of the blocks from the array.

We want WP_Theme_JSON to be ignorant of the implementation details of how the CSS is being used.
This filter allows us to modify the output of WP_Theme_JSON depending on whether or not we are loading separate assets, without making the class aware of that detail.

Performance profile

How much work a call to wp_filter_out_block_nodes() 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
6

Executed per call on PHP 8.5. The body compiles to 14.

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 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_filter_out_block_nodes() 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.
