Performance profile

How much work a call to image_link_input_fields() 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

56–62

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 64.

Plugin surface

None

Nothing here hands control to plugin code.

Called by

1

1 place in core call this, so the cost is paid more often than your own code shows.

What it touches

• querycontent queryget_post()one call below image_link_input_fields()
• hookthird-party callbacksapply_filters()one call below image_link_input_fields()
• optionoption read or writeget_option()one call below image_link_input_fields()

Further down the call graph this can also reach 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 · 2 distinct outcomes

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