Performance profile

How much work a call to wp_apply_typography_support() 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

151–210

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 368.

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 · 2 distinct outcomes

One number would be a lie: the work depends on which branch runs. These are every distinct cost wp_apply_typography_support() 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.

Uses · 4

• wp_should_skip_block_supports_serialization()Checks whether serialization of the current block's supported properties should occur.
• wp_get_typography_font_size_value()Returns a font-size value based on a given font-size preset.
• wp_typography_get_preset_inline_style_value()Generates an inline style value for a typography feature e.g. text decoration, text transform, and font style.
• wp_style_engine_get_styles()Global public interface method to generate styles from a single style object, e.g. the value of a block's attributes.style object or the top level styles in theme.json.
