Performance profile

How much work a call to wp_media_insert_url_form() 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

Moderate

Reads stored settings via get_option(), cached per request but not free on a cold cache.

Scaling

Constant

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

Instructions

168–179

Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 186.

Plugin surface

1 hook

Third-party callbacks on 'disable_captions' run inside this call, and their cost is not bounded by anything here.

Called by

5

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

What it touches

• hookthird-party callbacksapply_filters()called directly
• optionoption read or writeget_option()called directly
• cacheobject cachewp_cache_get()one call below wp_media_insert_url_form()
• serializeserialisationmaybe_unserialize()one call below wp_media_insert_url_form()

Further down the call graph this can also reach query 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 wp_media_insert_url_form() can have, taken from its control-flow graph on PHP 8.5.

Hooks and filters fired · 1
