twentyseventeen_scripts()

Compatibility

Present in every tracked release (6.7.7 to 7.1.0), and compiles on PHP 7.4 through 8.6-dev.

Performance profile

How much work a call to twentyseventeen_scripts() 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

Heavy

Reaches the database via get_post().

Scaling

Constant

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

Instructions

104–156

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 157.

Plugin surface

None

Nothing here hands control to plugin code.

Further down the call graph this can also reach transient. That is the worst case, several calls deep and usually down an error path, not what a normal call pays.

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