Performance profile

How much work a call to _remove_theme_attribute_in_block_template_content() 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

Light

Touches nothing outside its own arguments.

Scaling

Scales with input

The body loops, so the work grows with what you pass in.

Instructions

20–24

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 42.

Plugin surface

None

Nothing here hands control to plugin code.

What it touches

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

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 _remove_theme_attribute_in_block_template_content() can have, taken from its control-flow graph on PHP 8.5.
